Sometimes, you can work out

percentages easily. At other times, you

may have to estimate.

There are 100 squares in this grid.

50% are Red27% are Yellow23% are Green

There are some quicker methods to

help you find different

percentages of amounts:

To find 50% of a number, divide it by 2...

50% of 40 = 20

To find 25% of a number, divide it by 4...25% of 40 = 10

To find 75% of a number, find 25% and thenmultiply that by 3...

75% of 40 = 30

To find 1% of a number, divide it by 100...

1% of 300 = 3

To find 10% of a number, divide it by 10...10% of 500 = 50

If the percentage is a multiple of 10, use the

method above to help you.

20% of 500 = 10030% of 500 = 15040% of 500 = 200

Could you combine any of these methods to find

11% of a number...or 85% of a number?
