The amount of the increase is ($150 - $125) = $25 .
As a fraction of the original amount, $25 is
$25/$125 = 1/5 of the original amount .
The increase was 1/5 .
1/5 means 1 divided by 5.
To change a fraction into a decimal, do the division:
1/5 = 1 divided by 5 = 0.20 .
To turn a decimal into a percent,
move the decimal point 2 spaces that way ===> .
0.20 = 20 %
