Question

If elephant grass grows 3 2/5 inches a day, how many inches will it grow in 7 days?

Answer 1

119/5 or 23.8 inches

3 2/5 times 7 will give you your answer. Switch 3 and 2/5 (mixed fraction) to an improper fraction. There’s 3 wholes so 3 x 5 = 15 plus the 2 in the numerator. That will be 17/5 times 7. 17 x 7 = 119. This is still over the 5 denominator. You could keep it like that but I assume a 23.8 will look better.

Answer 2

Answer:

23 4/5 inches

Explanation:

3 2/5 = 3 + 2/5 = 15/5 + 2/5 = 17/5

7*17/5 = 119/5

119/5 = 115/5 + 4/5 = 23 + 4/5 = 23 4/5
