Jermaine’s Solution Mildred’s Solution5(-2 1/4) 5(-2 1/4) 5(-2 -1/4) 5(-2 -1/4)-10 -1/4 -10 -5/4-10 1/4 -11 1/4Which describes the reasoning used to determine whose solution is correct?A. Jermaine is correct because -10 -1/4 equals -10 1/4.B.Jermaine is correct because he distributed 5 correctly.C.Mildred is correct because she multiplied 5 by –2 but not by -1/4.D.Mildred is correct because she distributed 5 correctly.

Accepted Solution

A:
Mildred's solution is correct.

5(-2 1/4) = 5(-2 + -1/4) = 5(-2) + 5(-1/4) = -10 + -5/4 = -10 + -1 1/4 = -11 1/4
