You can calculate percentages by using "easy" percentages and then multiply or divide to find the "harder" percentage. The example below shows these two steps.

What is 30% of $40?

Step 1

What is 10% of $40?

10% of $40 = $40 ÷ 10 = $4

10% is a relatively easy percentage to find. It is the equivalent to one-tenth, or the same as dividing by 10. To divide by 10 we move the decimal point one place to the left.

Step 2

3 x $4 = $12

30% of $40 = $12

30% is 3 times ( 3 x) 10% so we multiply what 10% of $40 is by 3

Use the above steps to calculate the percentages fill in the blanks in the tables below. The first table is completed for you.

  10% 30%
$10 $1 $3
$20 $2 $6
$40 $4 $12
  10% 40%
$50 $5 $20
$70 $7 $28
$90 $9 $36
  10% 70%
$40 $4 $28
$80 $8 $56
$200 $20 $140
  10% 90%
$10 $1 $9
$20 $2 $18
$40 $4 $36
  10% 20%
$5 $0.50 $1
$4 $0.40 $0.80
$8 $0.80 $1.60
  10% 60%
$100 $10 $60
$200 $20 $120
$50 $5 $30
