A few easy examples

Example one

60% of 900 = ???

(900/100) x 60 = 540

First we check how much is one percent: we divide 900 by 100. We get 9.
Then we multiply one percent by 60 (60% = 60 per hundred = 60 percent) so 9 x 60 = 540.

Example two

90 = ??? % of 125

90 x (100/125) = 72 %

First we calculate how much is one unit: we divide 125 by 100.
Then we multiply one unit by 90 because we want to know how much is 90 units.
In this way we calculate the percentage.

Example three

What is the % change from 150 to 190?

(190-150) x (100/150) = 26.66 %

150 represents 100%. So the percent of one unit is represented by 100/150.
190-150 is 40. So 40 units present 40 x (100/150) = 26.66 %
In this way we calculate the percentage increase or decrease.
