Question

Harriet had a 2 1/4-foot length of board. She will use 1 2/3 feet for a project today. How many feet of board will remain

Answer 1

2 1/4 = 9/4 and 1 2/3 = 5/3

board remaining = 9/4 - 5/3 = 27/12 - 20/12 = 7/12

Answer 2

9/4 - 5/3 = 7/12

Answer 3

\[\left(2\frac{1}{4}\right)-\left(1\frac{2}{3}\right)=\frac{7}{12} \]
