Is cross-simplifying the product of fractions taught anywhere on Khan Academy?

I don’t know of vid or article that explains it, but I do know of a vid that had cross multiplication in it, and I think that he did explain it a little bit, if that helps. It was somewhere in my pre algebra course. I’ll have to review the vid to see how much he actually explained about it.

If you want I can probably find it. It was about different ways to do a question that involved fractions and one of the ways was cross multiplication of the fractions.

Bookworm,

I'm not talking about cross multiplication, but cross simplification -- the numerator of one fraction and the denominator of a different fraction are each divided by the same number before the fractions are multiplied together.

If you find a video or article that explains cross simplification well, I'd be grateful for the reference (you can share course, unit, lesson, title if that's easier than a link; timestamp or section header would be helpful too).  

Do you agree that Khan Academy should teach cross simplification before using the technique in a video on another topic?

Oh, ok, sorry.

👍🏽. I’ll see if I can find something.

Yes, I totally agree

Is this close to what I should be looking for? This vid at 2:29 https://www.khanacademy.org/math/cc-sixth-grade-math/cc-6th-arithmetic-operations/cc-6th-dividing-fractions/v/dividing-mixed-numbers-example
