Question

a tree was 12 3/8 inches tall when it was first planted. three years later the tree was 21 1/8 inches tall how much did the tree grow in the 3 years?​

Answer 1

The tree grew 8 and 3/4 inches.

Explanation:

To get this answer, first subtract the whole numbers.

21 - 12 = 9

Now do the same with the fractions.

1/8 - 3/8 = -2/8

Now add those two together.

9 - 2/8 = 8 6/8 = 8 3/4
