Applying cross multiplication to solve a proportion

👉 Learn how to solve proportions. Two ratios are said to be proportional when the two ratios are equal. Thus, proportion problems are problems involving the equality of two ratios. When given a proportion problem with an unknown, we usually cross-multiply the two ratios and then solve for the unknown using the applicable operations.

I learned this in grade 8 now I’m in grade 11 forgetting how to do this

[AnthonyTylerr]

When the guy said "2 over 12." I felt that.

Was never taught cross multiply, always did it the old fashioned way so as a senior I’m learning this now lol
Nice lesson

[RogueRubio]

You explained it perfectly. I also like how you teach/interact with your student. I can tell you’re a great teacher.

Literally all I needed was to read your video title, and realize "oh, that's a thing." Nothing else. Just your video title. THANK YOU.

The fact that he explained why we have to divide the 3x by 3 was chef's kiss. I always didn't connect the dots that you do one operation to undo its opposite operation, that small detail was never explain to me but this video did😭💗

ur students r so lucky to have u as their math teacher

[shahdkarout]

Omg I wish this guy was my math teacher😂😂😂

For this question, theres an next way which is say:
You have 2/3 and they say it’s = to x/24 you can make it equivalent. So divide both denominators and use the answer you get from dividing it and multiply it by the numerator.
Eg. 4/8 = 24/x. Divide the numerators and multiply that answer to the denominator.
4x6 = 24

8x6 48

I'm in pharmacy school and believe me when I tell you. I needed to refresh my understanding of this for RX calculations. Glad this video exists :)

[alyssamartinez]

In the 10 grade learning this for chemistry 💀

[oumaくん]

[slystar]

This is probably the greatest math teacher ever! Thank you!!

[ShawntiaKnott]

Currently 22. Never learned how to do this.

Graduated back in 2015, but I loved cross multiplication with a variable so much I had to refresh my memory! Awesome lesson. 😎🍻

[melvinchundi]

thank u so much 😭 im stuck at the question trying to remember this
