Question

A kudzu plant is 1 6/7 feet tall. Over time, the plant grows to 4 2/9 feet. About how much does the plant grow ? Use rounding to estimate

Answer 1

The correct answer is 2 23/63

Explanation:

To determine how much the plant grew, start by subtracting the starting whole number value from the ending whole number value.

4 - 1 = 3

Now do the same with the fractions. Use common denominators.

2/9 - 6/7

14/63 - 54/63

-40/63

Now add the two numbers together.

3 - 40/63 = 2 23/63
