Answer 1

Travis cuts 125 whole 2/5 inches wide strip if the percent of error was 10% the actual length of the strips he needs to cut was 114 inches

What is the percentage?

It is defined as the ratio of two numbers expressed in the fraction of 100 parts. It is the measure to compare two data, the % sign is used to express the percentage.

We have:

The length Travis needs to cut = 114 inches

Percent of error = 10%

Let's assume he cuts x inches wide strip

So from the percent of error formula:

$\rm \dfrac{x-114}{114} = \dfrac{10}{100}$

$\rm x = \dfrac{114}{10}+114$

$\rm x = \dfrac{1254}{10}\Rightarrow \dfrac {627}{5}$  or

$\rm x = 125\dfrac{2}{5} \ inches$  

Thus, Travis cuts 125 whole 2/5 inches wide strip if the percent of error was 10% the actual length of the strips he needs to cut was 114 inches
