I shall explain in setps
numerator = 16x^2y^2+24x^3y
take the GCD as common factor and factorise( 8 devides both so x^2 and y hence 8x^2y
8x^2y(2y+3x)
now denominaotor
= 8x^3y^2-4x^2y = 4x^2y(2xy-1)
devide to get 8x^2y(2y+3x)/(4x^2y(2xy-1)) = 2(2y+3x)/(2xy-1)

Okay...first off looks like you omitted the ^ sign
right after the 24X in your question... if I am correct
and you did mean it to read 24X^3Y

then lets write it as:

16X^2Y^2 + 24X^3Y
-------------------------
8X^3Y^2 - 4X^2Y

Divide the whole thing by 4X^2Y
Because 4 is the largest thing that can go into all the numbers, and X^2 is the largest value of X in "all" the
groupings, and Y is the largest value of Y in "all" the
groupings.

So you are left with

4Y + 6X
-----------
2XY - 1

Hope that helps you out.
