1. Straight to the point. 2. Easy to understand and implement. Freaking BRILLIANT!! Thanks a million. Wish I had seen this before watching countless other (long, boring) methods.
You just unboggled the mind of a 42 years first time algebra student. THANK YOU. I read my text several times and didn't understand until I watched your video. God Bless
For Pete's sake this is brilliant video-filming technique: put a window between yourself and the camera. The camera records in a mirrored view. Flip the clip horizontally and that's the waaaaayyy the news goes.
Yes! She isn't even left handed actually but it looks that way because of the flip.
I thought she learned to write left handed and backwards.
Wow!! I've been having such a hard time trying to understand LCM. You made it easy to understand! Thanks!!
multiples of 12 : 12, 24, 36, 48, 60
multiples of 30 : 30, 60
LCM is 60 (this is what i call fast) i think finding the multiples is much easier than finding the common factors.
Mark, you just saved my life!! I'm 48, and back in school. Why can't people just explain this! Thanks, man!
Nobody asked you
@@savalangustafson1820 wow so mean this person worked so bad on this ideo
i think it depends on the situation
I've struggled with maths my entire life and explanations like this make me so happy. I CAN DO THIS!
That was awesome! Thank you, Maria. I needed this refresher for a little exam I have coming up with the district.
I have always found finding LCD and LCM tedious and struggled in math. I wish I had learned this when I was a child.
WOW THANK U SO MUCH I WAS FREAKING OUT BECAUSE MY TEACHER IS SOOOOO CONFUSING BUT THANK U THANK U THANK U SOOOOO MUCH
SHUT UP
Nice comeback bro
@@Kyriii366 bruh whats wrong with you
@@ianx_3q whats wrong what
Short and precisely demonstrated, very good method, exactly what I was looking for! Great video, thank you very much
Some things are worth reviewing back, thanks a lot for the quick refresh,Ma'am. I almost lost myself earlier on my seatwork >.<
My technique is to just keep adding the Base Denominator until both sides reaches equal.
12 - 24 36 48 60
30 - 60
And we got 60 as our LCM.
This is great, thanks.I really struggled with other methods and made mistakes.
Thank you I just came from another demonstration and it was much more complex, thanks this is great and easy to remember....
Thank you for being so succinct!!! This should go down well with students.
OMG....thank you, thank you, thank you! This helped me so much, I've been banging my head for almost week trying to get it to click in my brain!!!
Awesome way but I learn it in a different way but you teach a good way to find a common factor. Thnx today I learn something new.
This is a really great way of explaining how to find the LCD - however.. I am helping my son (4th grader) with Ordering Fractions and this one is a bit longer to sort.
4/9,2/6,15/21,7/12,9/18
I certainly can use a Multiplication Chart and find that 252 is the LCD but I don’t know how to lay this out as it’s been done in this video.
Short, easy and sweet!! you are a life saver!
Thanks for sharing this method "division ladder" it was easy to follow and apply when finding the LCD.
Me: goes on Safari searches up “what’s the least common denominator of (so and so)”
lol but you can’t do it on tests
What about for finding the LCM of 3 numbers such as 12, 30 and 25?
Thank you EHOW, best method i've ever come across
This video just saved my life, Thank you so much!
Thanks Maria. It really helped
Thank you so much, very helpful video
Thank You so much. Following you from now on
I've never seen this method before. Thank you!
Maria, thank you. I was looking for the easiest way to find the LCD, and you showed me how to find it in a second without any too much thinking. Great job keep it up I will waiting for more of your nice and short clips.
WOW. I have no words for this.
I would love to learn how you are projecting this -- or are you just writing backwards on a big window?
Renaud Beserie-Stauber NO STUPID
Does this only work for 2 numbers? Would this work for 3, 5, and 7?
ok so im turning grade 7 soon any tips on wut should i review? while quarantine?
Thank you Maria!
Reply please, did you write everything right side up or normal?
Nice Maria, I like your style!
Thank you for helping
She just changed my life. One love
Wow impressive!
Love this! Great for kids with dyscalculia
Do you give tutoring in pre calculus.
Love you Marija! ❤
how do I put this.... thank you.... you just made this so much easier and less of a hassle
Wow. amazing teacher!
Super nice job! Excellent video ; ) Thank you so much!
I loved this thank you so much
This is amazing thanks!
Thank you for this video
That was excellent. Thank you!!!
You can just multiply 12 and 5 or 30 and 2 that will just the same as 60, you just like cross multiply and get the same answer
This is amazing! Helped me so much!
It's really easy. Please do a few difficult questions. I remember doing these in the 5th grade.
That is really helpful to me😊
Marija Marijaaaaa is a Mathmatical Rock Star
Awesome she makes it so easy to get thank u !!!
Yah🤓🤓😊😊😊thanks so much Ma'm...im going Crazy without these Lessons in our Periodical test!!!.....😀😀😀😄😄😅😅
Thank you that was very helpful
Thanks it will help to my assignment
hello am new.... how u do that . is it easy for u . common denominator. is different larger and smaller number. how that figure out.
THANK YOU PROFESSOR,
Great work, keep it up!
very good and very well explained!
Can the ladder method be used to find HCF & LCM for 3 numbers too ?? if yes then pls post a video on that .
Thank you! I was struggling in class with this but you helped me!
You saved my life! thanks!!!
🖕👙
You're amazing. Your video helped me so much.
what about 6 and 12.
the lcm is 12 but if u do your method, u get 36
Thank btw, I have online class but idk how to find the LCD but this helped me, thx
Great video i am totally going to like this vid!
thank you sooo much i have learn soo much
Thank you! super helpful for my 11 year old.
THANK YOU SO MUCH THIS SO MUCH SIMPLER THAN THE WAY MY TEACHER TAUGHT IT AND I WAS SO CONFUSED
This doesn't help either. I need more examples. WHat happens if their prime numbers??? I fucking hate math so much.
Daniel Despres Then multiply with the largest number and check divisibility rules.. If not keep repeating the proccess...
I just love how Mathematics has tons of ways to solve a single problem and ending up with the same answer
If you know without a doubt that the largest number is prime, then the LCM would be the two numbers multiplied together, no matter what number the smaller number is.
If you know the smaller number is prime, you just have to see if the bigger number is divisible by it, if it is, the LCM is the bigger number, if it isn't, the LCM is the two numbers multiplied together again.
Therefore, prime numbers can actually make it a lot easier if you know they are prime with 100% certainty.
Daniel Despres no need to curse god!
Fuck.
shit.
It's the internet. It's the human language. People swear. The world is dark. It's harsh. Deal with it. Political correctness is the reason we have Trump as a president... Look how that turned out.
Can't take away people's right to free speech.
I just tried this with 5 and 7. I got 1 (1 and done) then formed the "L" and multiplied 1,5 and 7 to get 35.
thank you for this
how about 2,3,4, and 5? how to get the LCD of all these at once?
Fastest way to get to a lowest common denominator: read a controversial youtube post. But great vid!!!!
Finally i get!! Thank you so much.
HalTuberman exactly
thank you teacher.
Numbers 30 and 64, my text book rambled for 2 pages. Your method did it much faster and succinctly. Thanks
You Marija are amazing!!! Thank you so much!!!
The is the absolute best and FASTEST!!
THANKKKK YOU, I was struggling
Does this also work with 3 denominators or +
what were you writing on
dang, you made it easy ! thank you Maria (:
Cool!! Thanks!!
How does it work for 7 and 9 as nothing will divide into those two?
Can this be done with more than two numbers?
thanks soooooooo much this is so helpful.
what about LCD of 12, 21, and 28? This method does not work for 12, 21 and 28 because there is no number other than 1 that goes into all 12, 21 and 28.
THANK YOU!!!
I try this with odd number for example 3 and 11 and it doesnt seem to work, am I doing it wrong? do I have to choose a number the can divide each denominator equally?
The number needs to work with both numbers. For example, 7 and 28, both of these numbers can be divided by 7. So, you use 7 and write out the answers under the upside down division sign and write the 7 to the side.
the LCD of 3 and 11 is very obvious, just multiply 3 and 11. haha
thank you so much
THANK YOU SO MUCH FOR THIS
love it thanks!
Great idea
We are having trouble with 81/140 - 67/105. For the first tier of the ladder I get 5. The second tier I get 7 and the 3rd tier we get 1. However, your method doesn't seem to work as the final product I get is 420. What am I doing wrong?
Holy shit. I'm in college taking beginning algebra in my 40s and I completely forgot how to do all this stuff and this method just saved me a bunch of time
Language as like Tom Jones sang “ She’s a Lady”! Keep it clean.
Why? I swear like a sailor because I was one for 14 years. Fuck right off snowflake.
@@Jimihendrix1834
Should I use prime numbers?
This was actually helpful
I love you! Thank you!
Thank thank u so much my am gana deppres in this subject thank my tr. All ways have assiments and manny Quiz thank for this vedio
