A plant grew 1 1/2inches in 4 days. Then it grew 4/5 inch in 2 1/2 days What was the plants average
rate of growth during the entire time?

plant grew, on average, 23/65 inches per day

Step-by-step explanation:

average = total growth / total # days

avg = (1 1/2 + 4/5) ÷ 6 1/2

change mixed number to improper fractions:

avg = (3/2 + 4/5) ÷ 13/2

create equivalent fractions using a common denominator of 10:

avg = (15/10 + 8/10) ÷ 65/10

avg = 23/10 ÷ 65/10

avg = 23/10 x 10/65

avg = 23/65

plant grew, on average, 23/65 inches per day
