Question

Max measures and records his height every year. This year, as a fifth grader, his height is 5 1/6 feet. He has grown 1 1/4 feet since he was in second grade. What was Max's height when he was in second grade?

Answer 1

3 11/12 feet

Explanation:

(5 1/6 ft) - (1 1/4 ft) = (5 2/12 ft) - (1 3/12 ft) = (5 -1) ft +(2/12 -3/12) ft

= 4 ft - 1/12 ft

= 3 11/12 ft . . . . Max's height in second grade
