1. Fractions with Cancelling (IGCSE)
Hey there guys, I got a question on IGCSE fraction + cancelling,

The question is this (sorry I don't know how to use the special signs here, sorry I'm new):

(2y^2 / x^3) / (4y/x)

The answer I got was: y / (2x^2)

because the y on the right cancels out the *^2 on the y on the left, then the right x cancels out the *^3 on the x on the left into x^2 - then the 2 and 4 (left and right) cancel into 1 (not shown on my answer ofcourse) and 2

so essentially I got:

= (y / x^2) / 2

Then the / 2 turns into (Times) 1/2 because the 2 is: 2/1 thus you invert the second fraction and then

(y / x^2) x 1/2 = (y/2x^2)

which is my final answer, Does this answer seem correct? - I've tried it for a while, but not sure how else I can do this question, anyone think I've made a mistake? Thanks for reading =)

Thanks guys, (Doing IGCSE at my age (14) is a little difficult at some stages, but it's quite nice, I <3 MATHS!)

and thanks for checking the calculations all the way through, that's definite marks if it came up in the exam!
