Best ResponseYou've already chosen the best response.0Since six is the whole, it will be your base, just like saying the frame was 5.43 feet out of six

Best ResponseYou've already chosen the best response.0Well let's look at an easier version of the problem. If I have 67 cents, what percent of a dollar do I have?

Best ResponseYou've already chosen the best response.0Well there are 100 cents in one dollar, and we have 67 out of 100, or 67/100

Best ResponseYou've already chosen the best response.0In decimal form that is 0.67. To convert to a percent we would move the decimal place to the right two points, or multiply by 100

Best ResponseYou've already chosen the best response.0Your problem is similar, except we're looking for a percent difference between his measurement and the actual dimensions. So we can say 5.43/6

Best ResponseYou've already chosen the best response.0This will give you what percent of the window he measured, to get the percent difference, you can subtract that answer from 100. You should get 9.5%

Best ResponseYou've already chosen the best response.0***5.43 feet, but the actual height was 6 feet. What is the percentage of error*** before finding the percent error, you need to find the error in feet For example, if he measured 6 ft he would be exactly right, and have 0 error if he measured 5 ft, he would be off by 1 foot. the error would be 1 ft here the error is the difference between 6 and 5.43 6.00  5.43 = 0.57 now we can find percent error: first find the fraction error/true 0.57/6.00 second, change that to a decimal. (hopefully you know how to do that) you get 0.095 third, change a decimal to a percent. (per cent is Latin for "per one hundred") multiply top and bottom by 100: \[ \frac{0.095}{1} \cdot \frac{100}{100} = \frac{9.5}{100} \] that shows 9.5 per hundred, which we can also write as 9.5% (the % means per hundred, i.e. divide by 100)
