Question

Scott was 63 3/8 inches tall when he started seventh grade and 65 1/4 inches tall when he started eighth grade. How many inches did he grow per month during this time? 

Answer 1

EXPLANATION

We must turn 63 3/8 and 65 1/4 into improper fractions and subtract them as follows:

63 3/8 = 507/8

65 1/4 = 261/4

Subtracting both fractions:

261/4 - 507/8 = 15/8 = 1 7/8 = 1.875

Answer: He grew up 1 7/8 inches during this time.
