Follow PEMDAS (Paren's first, Exponentiation, Multiplication and Division (L to R), Addition and Subtraction (L to R)):

Numerator, N: 12(3/4)^2 = 12*9/16 = 27/4 <<< (a/b)^2 = (a^2)/(b^2), do the exponentiation first, then multiply by 12.
Denominator, D: 10y = 10(3/5) = 30/5 = 6
N/D = (27/4)/6 = 27/24 =

If you post your work we tutors can point out where you are going off track.

In the last line I did (27/4)/6 = (27/4)*(1/6) = (27*1)/(4*6) �. just wanted to clarify how that gets to 27/24
