Carlene bought 8 1/6 yards of ribbon to decorate a shirt she only used 5 1/2 yards how muck ribbon does she have left over

Carlene has 2 8/12 yards of ribbon left over.

First) You write the problem.Then find a common denominator for both fractions (common denominator is 12 since 6 x 2 = 12 and 2 x 6= 12)

Second)You write equivalent fractions that end with a denominator of 12. (8 2/12 and 5 6/12)

Third)You need to rename the mixed numbers since you cannot take away 6/12 from 2/12. ( Rename the numbers as 7 14/12 and keep the 5 6/12 the same)

Lastly, you subtract the whole numbers, and the numerators and get your answer of 2 8/12.

Hope this helps!
