Question

Kathy has a piece of cloth she used 1/7 of the cloth to make a pillowcase and 1/4 of the cloth to make a tablecloth how much of the cloth did Kathy have

Answer 1

Explanation:

she used 1/4+1/7 of the cloth
lcm of 1/4 and 1/7 is 28
1/4 becomes 7/28
1/7 becomes 4/28
7+4/28 = 11/28
therefore, she used 11/28 of the cloth and now has 17/28 of the cloth left
