50% 75% 1% 99% 0.1% 25% 5% 23% 10% 2.3% 0.023 0.05 0.1 0.5 0.75 0.01 0.23 0.99 0.25 0.001 Pen (press esc to cancel) Here are some percentages and decimals. Match them up with their decimal equivalent.

Percentages with multipliers We can use these decimal equivalents to work out percentages on a calculator nice and quickly. Example. 63% of 765 The multiplier for this percentage is 0.63 ( notice it’s the same as the decimal equivalent) So 63% of 765 = 0.63 x 765 = 481.95 Remember – to change a percentage to a decimal you have to divide it by 100!

Percentages with multipliers Here is another example Example. 7% of 48 The multiplier for this percentage is 0.07 ( not 0.7 as some people might think) So 7% of 48 = 0.07 x 48 = 3.36

6% of 490 72% of 150 12% of 435 99% of 340 3% of 693 24% of 80 108 336.6 20.79 19.2 52.2 294 Pen (press esc to cancel) Now try these using your calculator

Percentages with multipliers Now it’s your turn. Use your calculator and what you now know about multipliers to complete the crossnumber.
