Question

Sam plans to walk his dog a distance of 1 mile.He walks 3/8 of a mile and stops to get a bottle of water.Then he walks 1/8 of a mile more and stops to say hello to a friend.How far does Sam still have to walk his dog?

Answer 1

Add up the distances he has walked so far.

3/8 + 1/8 = 4/8

1 is the same thing as 8/8. So subtract the distance he has walked from 8/8.

8/8 - 4/8 = 4/8 miles or 0.5 miles
