### QUESTION 1 of 10

This worksheet is about finding a percentage of a number.

It is easy to find 10% of a number. You just divide the number by 10, because 10% means

 10 100
or
 1 10

When you know 10%, you can find other simple percentages.

5%   (÷ 2)

20% (× 2)

40% (× 4)

45% (40% + 5%)

and so on.

Example

Find 65% of 340.

10% is 34

5% is 34 ÷ 2 = 17

60% is 6 × 34 = 204

65% of 340 = 204 + 17 = 221
