Understanding percentage decrease is a key skill for the 11+ maths exam. It helps your child spot when an amount has gone down and by how much, using clear steps.

Worked example
A coat costs £80 but is now on sale for £60. What is the percentage decrease?
Step 1: Find the difference. £60 - £80 = -£20
Step 2: Divide by the original price. -£20 ÷ £80 = -0.25
Step 3: Multiply by 100. -0.25 × 100 = -25
The price has decreased by 25%.
After working through this example, your child will know how to recognise and calculate a percentage decrease in real-life situations. They can now try similar questions to build confidence with percentage increase and decrease problems.
