I'm 67 years old, within 2 seconds of seeing this I doubled it up to 16 and 100, so the answer is 16 % . I was in a shop sometime ago and the assistant (I would say about 25yo)serving me had to use a calculator to work out 10% of £99.95
An old teacher explained the magic of the "Is/Of" Box - the same as in your last example. Would've saved me headaches if we had the internet back in '72! Thanks for the trip down memory lane 😀
10% of 50 is 5 (too low)... 20% of 50 is 10 (too high) so the answer is between 10 and 20%...
The difference between 5 and 8 (= 3) is bigger than 8 and 10 (= 2) so the answer must be higher than 15 and lower than 20%...
Can you guess the right answer already?
This is a downside of multiple choice questions: you can estimate the answer.
Of course you can calculate the correct answer as well... x% . 50 = 8 so x% = 8/50 = 16/100 = 16%
Or like this: x/100 . 50 = 8 so x/2 = 8 and x = 16%
A long time ago they taught us a formula. R=p/b where rate is the percent described in the problem ,base is the larger number and p is the smaller number . P=br and B=p/r divide 8 by 50. 8/50=16%.
simply use 100's so you turn 50 into 100 (50x2=100) so 8x2=16 so much faster and use the other math if the numbers don't give you easy multiple or dividable numbers.
Per cent means per 100. Therefore double both to get to 100 = 16
No. See my reply
That’s how I did it.
In the case of a multiple choice, an estimate can be used. Since 5 would be 10% of 50 and we know that 8>5. Check the options for an answer that is > 10%.
In that equation,you could do it,by multipling by 1/2,install of 50! X= 8× (1/2)= : Equivalent! Correction on above,should have been,"instead" of! The equation would work ultimate as 2× 8= 16!! Another work around,minus calculator! Pencil and Paper- Regent exams from 6th grade! Thank you,for the refresher course! Thank you 😇 😊!
B) 16%
technically, the question in the title of the video is different than the question in the video. The question in the title asks what percent is 8 of 50%, the question in the video asks what percent is 8 of 50.
No smiley face for John.
Agree, the title could have been worded better, but I think we all knew the intent
@@darkst0rm2 You are probably right.
re: "The question in the title asks what percent is 8 of 50%"
Wrong. The title clearly shows "8 is what percent of 50%" (meaning 8 = ?% of 50 >>> 8 = %50 >>> 8/50 = % >>>.16*100 = 16%
@@ab_ab_c "re: "The question in the title asks what percent is 8 of 50%"
Wrong" um here is an exact quote of the video title: "8 is what percent of 50% A SIMPLE Percent question that MANY will get WRONG!" it is asking what percent is 8 of 50%. or in other words 8 is what percent of 50%. Also 16% would be correct if asked 8 is what percent of 50, but it asked 8 is what percent of 50%. (that would be 8/.50 which = 1600%.
At the title card, I believe the answer is b) 16%.
Let's start by writing the problem as 50 * p = 8, with p being the percentage.
Divide both sides by the 50: p = 0.16, or 16%.
It is a fraction 8 over 50. Just divide 8 by 50 and move the decimal left 2 places to get 16%. Just by inspection you know it is just under 20%.
You make math so much fun! 👍
part/whole*100 = percentage
8/50*100=16%
Thank you
Since 50 is a multiple of 100, simply multiply by 2 so it becomes, 16 is what % of 100?
I knew the answer on site, don't know how I do that. I hated math until I went to a Technical college years later. I had an instructor who taught me a whole different approach to math.
I had 5x10=50 and that 10 was 20% memorized in large part due to $ currency practice. 8 was close to 10, so I figured the 8 was a smaller number and therefore a slightly smaller percentage, and 16 was the closest answer choice. INTJ brain.
Now, my Dad used to find errors in math texts and tests all the time (possibly using a similar technique to see that something was wrong), and he would go talk to the teachers, so you can’t always trust that method of test taking. For this one, it worked to just kind of see the answer, but clearly it could have been made more challenging.
Even if you were bad at percentages, you could still use the process of elimination which you sort of showed here (with the 4% example) and We can use our basic knowledge of tens I guess( 10% and 20%) for example. We can figure in our head that 10% of 50 is 5, but that's smaller than 8, so it's more than 10%. But 20% of 50 is 10, which is greater than 8, so the answer lies between 10% and 20%. You could also go further (or skip and try answer C) since 32% is roughly 1/3. If you were to divide 50 by 3 you would get 16.67 technically, but quick math would lead you to roughly 15 which would at least tell you the percentage is still too high (as even 15 is greater than 8), so it can't be 32%. And lastly 44% is close enough to 50% that you can conclude again that roughly 50% of 50 is 25, still too large. So if you really didn't know how to do the percentages you could use this method to narrow it down but it would take longer. But by estimating what the percentages equal you can narrow down the answer (in this problem at least) pretty quickly and that's what is being showed, but in a more detailed manner I guess. But if you know how to quickly calculate values based on 10% increments it can make this go faster (10% of 50, drop the 0 so 5, 20% is double 10% so multiply 5 by 2 and get 10, too large).
16%
The ‘trick’ is built into question (8) is what percent of 50%. = 8 is 8% of 100 therefore 8 is 16% of 50%
Double 50 then double 8 =16
I wouldnt' have thought of that. thanks
I just did it like this.
Yes I know my math skills suck
50% of 50 is 25.
50% of 25 is 12 1/2
That puts us at 25%
50% of 12 1/2 is 6 1/4
Thats 12 1/2 percent
Since 8 is higher than 6 1/4
And the next highest choice after 12 is 16. Thats the correct number.
🤗
lol never thought I’d be doing a math test . Fun 🎉
It just seems so simple to think that X/100 =8/50. . . X=800/50. . .. 800/50 =16. X=16. (Instead of calculating out all those options).
Easy× 8 by 3.142 ,divide by the square root of pi then multiple by your age.
I instantly knew that 10% of 50 is 5 and 20% of 50 is 10 and with 8 being between 5 and 10, the % answer must be 16 and this was easy to test as per all the methods to actually calculate it.
I’m rubbish at maths. Had a dreadful maths teacher at school who struck the fear of god into me. Hence I grew up dreading maths. However, I’m strangely fascinated by it too and love watching your lessons 🙏
16
8 = 8% of 100
50 = 100/2
8x2 = 16
Ergo 8 = 16% of 50.
This took me about 5 seconds, mainly because I'm 60 and therefore had a proper education.
Divide 100 by 50 and multiply by 2
If a bank gives 5.04% interest on deposit, is it lower or greater than .9%? Isnt 5.04% written as .00504 and .9% written as .009%? Please help, someone…Thank you…
It's 0.0504. You added a zero.
@@richardl6751 What he said. When you moved the decimal point on the 0.9%, you move it two places. When you moved the decimal point on the 5.04%, you moved it three places. From 5.04 to 0.504 is one place. From 0.504 to 0.0504 is one place.
My thought process was like: "8 is 8% of 100, and 50 is half of 100, hence 8 in 50 has to be double the % of 8 in 100"
I like how you think
One easy way of doing it, especially if your base number is 20, 25, 50, or 200. Piece of cake if your base is 100. Otherwise, just divide and change the decimal to percent by multiplying by 100.
There are many ways to solve each problem...
Simple. Multiply each by 2. 16%
(8*100)/50=80/5=16
As 5 is the 10% of 50, then 8 can only be a percentage between 10 and 20. Sixteen is the only option on the table.
A ns: 16
Nice I got it!
got it 16 .16 x 50 = 8 thanks for an easy one,
B). 16%.
(x-4x+4)
(x-3x+2)
50/100 = 0.5 is 1% ...1 is 2% 2 is 4 % 4 is 8 % therefore 8 is 16 %
Seems there's loads of comments making it really complicated. As others have mentioned just double it. I honestly thought I must have missed something it seemed so simple and spent far longer checking my logic made sense and I hadn't made some stupid mistake than it took to think about the problem to get the percentage and hence answer.
X% of 50 is the same as 50% of X, so if X% of 50 equals 8 then 50% of X also equals 8 making X equal to 16. Answer b)16%
b-16
(8x100)=800, (800÷50)=16, ans.= 16%
WP of WN = N
b)16%
(b)16%
2:01 this is a confusing question
meaning the confusion is the purpose of the question
8 is what % of 50
after solving the number N will fulfill:
8 = N × 50
8/50 = N
16/100 = N
0.16 = N
but % = 100
so
N = 16%
VERIFY
REPEAT
50×16% =?8
2×[50×16%=?8]
100×16% =? 16
16 = ❤ 16✔️
SORRY....
I am not thinking properly to ACCURATELY notate my steps.
refresh...
what is "%"
as a good definition a % is a part of 100. 1% is 1 part of 100. 10% is 10 parts of 100. Probably a good way to think about % is pennies to the dollar. Typically (¿always?) sales tax is given in %. 3% sales tax is 3 pennies to the dollar.
This problem is 8 is what percent of 50
or
8 pennies is what percent of 50 pemnies. Gotta normalize to 16 pennies to 100 pennies which is 16% of $1.
What percentage of infinity is 1?
Then 0 ...... ?
There is an answer...
Put it this way --- there is only one one. It can't be sub-divided, made smaller. In the same way 'infinity' can't be made greater (or can it?). One is next after zero. And either 'zero' is absolute - or one does not exist. Is one infinity????
Nay -- zero encompasses infinity. One zero, one infinity! There is an aspect to mathematical thinking not possible in this realm.
Infinity isn't a number, it's a concept. No matter how large a number you select, there will always be a larger number that exists. You cannot calculate a percentage on a concept, only on a number.
Your math problem as worded in the caption started a heated discussion between my brother and I, as asking "8 is what percent of 50%" is not the same as the problem that you show in the video. That 50% could be of any possible numerical figure, so the correct answer wouldn't be 16, but an algebraic figure of a percentage of X/2, X being the unknown number. I really can't work algebra in my mind, but maybe the answer is X/16%, but probably not.
These questions have always troubled me . Instead of 50% substitute 1% so the answer is 800%. Or eight percent of eight percent is 100%. Though correct it seems like the person must have stated the question poory.
10 is 20% of 50 so 8 must be 16%. Some weird flash thinking for 50 is 2 times number.
As
4%
16 by doubling all
That was my fourth option but you already took the honor.
Didn't know how to do the calculation so i know that 10 is 20% of 50 so 8 is closer and less than 10 so it has to be 16%, the closest answer to 20%
4
Divide...got ot...I multiplied
16 percent
When ever you need to find the percent of a number. I was taught the 1 percent method. 8 is what percent of 50? 50 has an invisible decimal at the end. Divide that number by 100 to get 1 percent. .5 or move the decimal left two places. Now 8 times 5 is 40. Remember to move the decimal. I got .4 or 4 percent is my answer. There can be different ways to do this question I'm sure
14%
I choose a...4.
B 16%
"is/of AKA IS over OF"
B - 16%
Wrong it's 16 percent. Double both 50 and 8. So it now says 16 is what percent of 100. Or self explanatory it's 16 percent. I messed up the first time
8/50 * 100 = 16%
50x2=100
8x2=16
16%
32
8÷50 is the same as 16÷100.
I only read the thumbnail picture and not the title. Confusing. But I think the answer is still the same.
%/100 = Is/Of. 16.
The answer is 16percent. 8over 50x 100 over 1
B? 16%🎉
8/50X100=16% and it is b)
8%… 50/100=.01x8=.08 or 8%
A.
Just because we can do math does not mean we can click mouse buttons.
Answer a) 4%
Your out by 4x100%😏
My answer is 16%
The answer is 16%
B = 16%
8=x•50/100
x=16
8=16%50
Maybe the correct answer is 16. 8 is 16 percent of 50 not 16% percent of 50
8 divided by 50 equal 0,16 equal 16%. So simple
16 per cent
b
Gotta be 16.
% means hundreth, so 8 fiftieths = 16 hundreths
Went the wrong way
16percent
16, 2x50=100, 2x8=16
(b)
8/50 = 16%...
Hey buddy, i dont need amyone reminding me of how bad i am at math. 😅
16 out of 100. guess is b, 16 percent. less than 20 percent
