You can calculate percentages by first finding what 10% of a value is and then what 5 or 1% is. From there you can multiply to find multiples and then add to get the required percentage. The example below shows this.

What is 35% of $40?

Step 1

What is 10% of $40?

10% of $40 = $40 ÷ 10 = $4

10% is a relatively easy percentage and can be found by dividing by 10.

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

Step 3

What is 5% of $40?

5% of $40 = $4 ÷ 2 = $2

5% is half of what 10% is so divide what 10% is by 2 .

Step 4

What is 35% of $40?

$12 + $2 = $14

Add what 30% is to what 5% is.

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% 5% 35%
$10 $1 $3 $0.50 $3.50
$20 $2 $6 $1 $7
$40 $4 $12 $2 $14
  10% 40% 5% 45%
$10 $1 $4 $0.50 $4.50
$20 $2 $8 $1 $9
$60 $6 $24 $3 $27
  10% 80% 5% 85%
$50 $5 $40 $2.50 $42.50
$90 $9 $72 $4.50 $76.50
$100 $10 $80 $5 $85
  10% 1% 2% 12%
$40 $4 $0.40 $0.80 $4.80
$60 $6 $0.60 $1.20 $7.20
$140 $14 $1.40 $2.80 $16.80
