Question

I just don't get algebraic fractions. I can solve them, but I don't get how it works. My teacher isn't very good at explaining. Could someone help me through this?

Answer 1

So for instance if I have
\[\frac{ 2xy }{ m } \times \frac{ 2m }{ y }\]
I know I can cancel the Y but I don't know why I can.
I can cancel the M, but the Y has been multiplied by X so it isn't Y anymore and removing one of them leaves you with XY - Y and that's more complicated. You can't just remove all the Ys because the first is X Ys and the second is one Y.

Answer 2

OH NO WAIT I GET IT
YOU'RE DIVIDING THE TOP BY THE BOTTOM SO XT DIVIDED BY Y IS JUST X IT ALL MAKES SENSE NOW

Answer 3

I'm sorry for being so stupid :I
