Question

Paulo had 2 1/4 feet of red twine. he had 1 5/12 feet of blue twine. he used some twine for a craft. he has 1 11/12 feet of twine left how much did he use for craft?

Answer 1

2 1/4 = 9/4 = 27/12

1 5/12 = 17/12

27/12 + 17/12 = 44/12

1 11/12 = 23/12

44/12 - 23/12 = 21/12 = 1 9/12

Paulo used 1 9/12 for crafting.

Answer 2

2 1/4 + 1 5/12 = 3 8/12

3 8/12 - 1 11/12 = 2 -1/4

he used 1 3/4 feet for a craft
