Anastasia had 10 buckets of mulch for her garden. If Colby used 3 2/7 buckets of Anastasia's mulch, how many buckets were left? Leave answer as a mixed number with a space between the whole number and the fraction
To answer this question you will subtract. We have a total amount of mulch that we are taking some away from. It would be 10 - 3 2/7. Here are two ways to show how to subtract.
1. Regroup the 10 whole to be able to subtract with common denominators.
10 = 9 7/7 - 3 2/7 = -3 2/7 6 5/7
or
2. Make 10 whole into an improper fraction with a denominator of 7.
