Question

Andrew mowed 1/2 of the yard on Saturday and 1/8 of the yard on Monday. What fraction of the yard still needs to be mowed?

Answer 1

First you find the common denominator, so 1/2 + 1/8 would instead be 4/8 + 1/8, which is 5/8. The equation would be 4/8+1/8=5/8, and 5/8 - 8/8 is 3/8. The fraction of the yard that still needs to be mowed is 3/8.

Answer 2

3 and 1 eighths of the yard still needs to be mowed.<span />
