1) Divide is to of 2.7 / 18.

= 0.152) Multiply answer by 100

0.15 x 100 = 15%

1) Write down formula Is = %of 100

2) Plug in your knowns.2.7 = x

18 100

3) Cross Multiply 18x = 270

80

• Write down formula• Is = % of 1002) Plug in your knowns.

17.6 = 22 x 1003) Cross Multiply

22x = 1,7604) Divide to get x by itself 22x = 1760

22 22x = 80

What to put on the note card

FINDING THE PERCENTAGE (IS)Example problem: 22% of 36 is x.

1) Turn 22% into a decimal.22% -> 0.22

x = 22 36 1003) Cross Multiply

100x = 7924) Divide to get x by itself 100x = 792

100 100 x = 7.92
