Question

Your estimate that the length of a board is 24 feet. The actual length of the board is 22 feet. Find the percent error.

Answer 1

9.09%

Explanation:

You over estimated by 2 feet. Find out how much 2 feet of 22 is by dividing 2 by 22...

2/22 = 0.090909090909

To convert a decimal to a percent, multiply the decimal by 100%

0.0909090909(100%) = 9.0909090909% or 9.09%
