Percentage multipliers

Percentage multipliers are a quick and powerful way to increase or decrease amounts in one step—like adding 20% VAT to a shopping bill or working out a 15% discount during a sale. Instead of doing two separate steps (finding the percentage, then adding or subtracting it), percentage multipliers let you do it all in one go with a single calculation. Jump to the questions
