Related Percentages

This series of percentage questions was designed for a class who had seen percentages many times, but were trying to “remember” how to find specific percentages. I wanted to draw attention to how it is possible to find any percentage using additive and multiplicative reasoning. Once pupils get the first question correct in each set, the others can be done by simply multiplying/dividing or adding up the previous answers in varying combinations.

I found it useful to use some diagrams when teaching this too.
