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.
Looking forward, students can then progress to additional number worksheets, for example a standard form worksheet or a rounding to decimal places worksheet.
