### Percentage change at a glance

Percentage change is the overall term for percentage increase and decrease. When something is increased by a given percentage, we can use mental calculation strategies or the percentage multiplier method to calculate its new value. For example, if something costs £35 and is increased by 20%, to find the new price we could either find 20% of £35 and add this to the original amount or work out 1.20 35.

If we were required instead to decrease by 20%, we could use subtraction from the original value, or use the percentage multiplier 0.8 (a 20% reduction means we are finding 80% of the original amount).

Sometimes, students are required to find the percentage change – for example, given the original and new values, calculate percentage profit or percentage loss. Extending this topic further, students study the reverse process – given the new number and the percentage change, work backwards to find the original number.

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