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

Vlada [557]

To find the decreased percentage,here's what we can do:
$\frac{originl \: value - new \: value}{originl \: value} \times 100\%$

In this case,the eqaution would be:
$\frac{280 - 210}{280} \times 100\% \\ = \frac{70}{280} \times 100\% \\ = \frac{1}{4} \times 100\% \\ = 25\%$
Hope it helps!
