A percentage multiplier is the decimal equivalent of a percentage, it is used to calculate percentages of amounts, percentage increase and percentage decrease.
When finding percentages of amounts, there are some quantities that students are expected to calculate mentally – such as 50%, 25%, 10%. For trickier amounts (e.g. 47% of 320), the decimal multiplier method is more efficient. We use the decimal equivalent of 47%, which is 0.47, and rewrite the calculation as 0.47 320.
When calculating percentage increase, we take account of the fact that we’re adding to the original amount (100%), so the percentage multiplier for an increase of 7% would be 1.07. When calculating percentage decrease, we’re subtracting from 100%, so the multiplier for a decrease of 12% would be 0.88 (1 – 0.12). This skill has lots of real-life applications, such as calculating sale prices. Repeated percentage change links to ideas such as interest rates and compound depreciation.
