Question

Find the percent of decrease from 280 to 210. Round to the nearest tenth of a percent, if necessary.

Answer 1

To find the decreased percentage,here's what we can do:

`(originl \: value - new \: value)/(originl \: value) * 100\%`

In this case,the eqaution would be:

`(280 - 210)/(280) * 100\% \\ = (70)/(280) * 100\% \\ = (1)/(4) * 100\% \\ = 25\%`
Hope it helps!
