Last month, you were 4.7 feet tall. This month, you are 4.87 feet tall. How much did you grow in a month

Answer 1

4.87 - 4.7 = 0.17 feet in a month = .17(12) = 2.04 inches

= slightly more than 2 inches in one month

However, that's treating 4.7 as if it were 4.70 accurate to 2 decimal places. 4.7 may have been rounded off from anywhere from 4.65 to 4.75. then the month's growth could be anywhere from 4.87-4.75 to 4.87-4.65 or 0.12 to 0.22 feet

or about 1.4 inches to 2.6 inches in a month
