How to work out a reverse percentage - GCSE maths question 7b

Показать описание

This video is all about how to work out a reverse percentage and forms part of the playlist reverse percentages.

This video is part b of the question that deals with a 4% increase and working out the original price. In this question the price of a rail ticket is £2828.80 after a 4% increase - we're asked to calculate the original price. The easiest way is to convert the percentage to a decimal and then use algebra to work through.


I hope the video helps and please do leave a comment - thanks!
