(100x^3y^2)/(64x^7y^4)

Please simplify completely :)

100/64 = 25/16
x^3 / x^7 = 1/x^4
y^2 / y^4 = 1/y^6
so (100x^3y^2)/(64x^7y^4)
=25/(16 x^4 y^6) 
wait isn't (y^2)/(y^4)=y^2?

nope
(y^2) times y^4 would be y^2, but you were dividing, so you have to subtract the exponents
2  4 = 6 
Ohh right thank you
