elena55 [62]
Wasnt sure if you were asking just for the standard form of that equation 
<span>(15y − 9 + 6y^2) + (10 − 5y) = 0 ) or if you wanted the equation simplified and then in standard form ( 6y^2 + 10y + 1 = 6 ) so i did both </span>

Choose the fraction that has not been reduced to simplest form.
EleoNora [17]

The answer would be (C).

To be fully simplified, the numerator and denominator must have a GCF of 1.

Answer (C) says 3/57. However, using the divisibility rule of 3 (add the digits together, and if the sum is a multiple of 3, then the number is as well), we see that 57 is divisible by 3, meaning this fraction is not simplified. The simplified version would be 1/19.
