Question: martha has a piece of cloth. she used 1/5 of the cloth to make a pillow case and another 5/9 of the cloth to make a tablecloth. a. what fraction of the cloth was used total for the pillow case and the tablecloth? b. what fraction of the cloth was left over? c. does martha have enough cloth left over to make another pillow case.

A) 1/5 + 5/9

find common denominator:
9*5 = 45

pillow case: 1/5 = 9/45
table cloth: 5/9 = 25/45

9/45 + 25/45 = 34/45 was used 

B. using 45 as the denominator the full piece of cloth would be 45/45
       fraction left over = 45/45 - 34/45 = 11/45 left

C. from A the pillow case uses 9/45, they have 11/45 left, because 9 is less than 11, they have enough to make a pillow case
