Give the equivalent numerator if the denominator is x³y².

x³y²
 For this case, the first thing you should know is the properties of the exponents.
 Let's write the full fraction:
 (1) / (x ^ 3 * y ^ 2)
 We have that by power properties:
 (1) / (x ^ 3 * y ^ 2) = x ^ -3 * y ^ -2
 Therefore the equivalent numerator is:
 x ^ -3 * y ^ -2
 
 x ^ -3 * y ^ -2

40%=2/550=1/230=3/1056=14/25

You can find the area of a rectangle by multiplying the length and height. so multiply 1/2*7/4(which is the simpler version of 1 3/4) and you get 7/8 as your answer.
