Boy, Teacher! 20% is 1/5 of 100, therefore 35 cents times 5 is 1.75
Yeah. Why go all round the houses
$0.35 = 20%(X)
X = $0.35/20%
= $0.35/0.2
= $1.75
3 seconds in my head.
Glad I can still think.
Solved in my head at the thumbnail in a matter of
multiply by 5. tada.
$1.75. Easy to solve in head. I like when he gives problems that I can use for food shopping, online shopping, cellphone contracts, etc..
$1.75
I don’t know how to use a calculator. We weren’t allowed to use them, so I never learned.
Okay, this may be a minor point, but my answer is One(1). The problem asks for an answer in dollars. The amount $.75 is not a dollar. So you do the math and the result is $1.75. That is correct. The problem is asking only for the number of dollars. There is no indication that the author wants to know the number of dollars and cents. And now you know why I majored in History and Economics.
If you'd majored in something more technical you might have learned the amazing and eye opening fact that not all numbers are integers.
The number of dollars is 1.75.
1.75 is a number.
@@gavindeane3670 You are absolutely correct. Sometimes the solution is not the answer. As my Dad used to say, "If you get the wrong answer, you have asked the wrong question." Math is fun stuff. I get about half of these math questions right.
You make in interesting point. The answer really does depend on how "dollars" is defined. And, you have pointed out an alternative definition. Having said that, the context of this problem is mathematical calculations, and a fractional part is almost always expected unless wording like "whole dollars" is used.
@@paulfrank8738 If this were a multiple choice problem, the correct answer would be listed. The correct answer is $1.75. All of my Mathite buddies like to talk about accuracy, precision, and repeatability. So, 1 divided by 1 is 1, so 0 divided by 0 should be 1. Instead it is undefined. Where is Newton when you need him.
@@paulfrank8738It's not that complicated. 1.75 is correct and 1 is incorrect.
On a strict interpretation of the wording of the question, you could argue that "one dollar and seventy-five cents" is incorrect because the question asks for a quantity of dollars not a quantity of dollars and cents. But in that case the correct answer is "one point seven five dollars".
Not all numbers are integers.
Greetings. The answer is 1 and 3/4 dollars.
If we assume that the value to be found is represented by X,
then. 20X/100=.35, and 20X=35 from which X=$35/20=$1.75.
got it $1.75 .35 X 5 = 1.75 easy thanks for the fun
1.75
$1.75 - done in my head - no calculator - liked this prob......
20% is 1/5 - so - .35 x 5 = 1.75
35¢ =.20 • x
0.35 = 1/5x
35/100 x 5/1= 175/100 =x x=1.75
1.75$
4% of 30=30*4/100
30*4/100=120/100
120/100=1.2
4% of x is 15
x=15/4*100
15/4*100=[3+(15-3*4)/4]100
15/4*100=[3+(15-12)/4]100
15/4*100=(3+3/4)100
15/4*100=[3.7+(30-7*4)/40]100
15/4*100=[3.7+(30-28)/40]100
15/4*100=(3.7+2/40)100
15/4*100=[3.75+(20-5*4)/400]100
15/4*100=[3.75+(20-20)/400]100
15/4*100=(3.75+0/400)100
15/4*100=3.75*100
x=3.75*100
x=375
35 cents is 20% of how many dollars?
x=$0.35/20*100
$0.35/20*100=[$0.01+(35-1*20)/2,000]100
$0.35/20*100=[$0.01+(35-20)/2,000]100
$0.35/20*100=($0.01+15/2,000)100
$0.35/20*100=[$0.017+(150-7*20)/20,000]100
$0.35/20*100=[$0.017+(150-140)/20,000]100
$0.35/20*100=($0.017+10/20,000)
$0.35/20*100=[$0.0175+(100-5*20)/200,000]100
$0.35/20*100=[$0.0175+(100-100)/200,000]100
$0.35/20*100=($0.0175+0/200,000)100
$0.35/20*100=$0.0175*100
x=$0.0175*100
x=$1.75
35 cents is 20%
1% is therefore 35/20 cents and 100% is 35/20 x 100 cents
100% is 175 cents which is $1.75
OR you can just say that 20% is 1/5th and multiply 35 cents by 5
Stop with the mmmmkays!! I feel like I’m watching South Park!
I have no idea at all. In my country we use DKK ad currency, and i dont know if it makes difference

.20X=.35
X=.35/.20
X= $1.75
Wonder how long would it take you if the percentage was 67 %🤔
If you call 67% 1/3 it is just as easy. Or calculator. 35 / .67
Of course 1:10 the two calculation have the same answer since there is no fractional penny
$X/5 = $0.35 = $1.75
20% goes 1,75 times into 35%. Then 1.75 dollars.
$ * .2 = .35
$ = .35 / .2 or .35 * 5
$ = 1.75
35/x = 20/100 or 35/x = 1/5
175
1 cent is 1% of $1. Cent is shorthand for percent.
Use a CALCULATOR? Anyone should be able to figure that out in their head or worse case with paper and pencil.
Oh wait a minute, I forgot that I'm older than dirt and for the most part teaching math is no longer taught without a calculator. Back in the day when I was working, I asked a fellow employee (college graduate) how many feet were in a mile and the answer was something like "Why should I know that? I can Google it."
100÷20=5×35=$1.75
1.75…. %20 is 1/5th of 1.00 5x.35 = 1.75
$.2X=.35 X=$1.75
35 divided by 2, divided by 10, 1.75.
$1.65
He made a simple, 4-second calculation ridiculously complicated. He's misleading and reprehensible.
17.50 sorry
Sooo Loooong 35¢ = 20% X$ -> $.35 = .2 $X -> $.35/.20 = $X -> $1.75 = $X.
0 trick question......
These are the problems that got me in trouble in school. The show your work thing. It is just 1.75 .
Why make it so horribly complicated? A 17 minute video when the explanation takes about 1 minute !!! 20% = 1 fifth, therefore the full amount = 5×35 = 175 = 1.75 dollars. What a waste of time - a 6year old could do it!! ( And the word is prob-lem, not proh-lem) Awful.
Guarantee you a 6-year-old who has never had a math class couldn't. You rant from the position of someone who already knows it and not the target audience of someone who has never been introduced to this before.
Obviously you are not a teacher. Solving a math problem and teaching how to solve the problem are two different things. Teaching means explaining and explaining requires time. He explained how to convert a percentage into a fraction and vice versa. There was also an explanation about American currency and he talked about the courses that he offers and about subscribing to his channel. This can't be done in a minute. He has more than 630k subscribers. There must be a reason for this. If you are not happy, you can always go somewhere else.
Wastes so much time on things I already know!
