Reverse Percentages
The below QQI Relay © shows one question at a time, and to proceed to the next question, you need to answer the current one correctly. Decide how many questions you want (you can always finish early if need be).
Choose which type of percentages you want to use (NonCalculator percentages are 1%, 5%, 10%, 20%, 25%, 50%, 75%).
Then decide if you want to have questions where the amount has been increased, decreased or a mixture of both by choosing Random.
Finally, by setting Multiplier to yes, you will be asked for the multiplier needed for the calculation, rather than the actual original amount.
When the questions appear, type your answer in the boxand click Check Answer to see if you are right. If correct, move on to the next question.

Ideas for Teachers
This activity requires each pupil to have access to a computer or other internet enabled device. They will each get a different random set of questions, and at the end you can see how they did in the results table. This is great for spicing up an activity as it adds an element of competition to the work.
Get them to set a high number of questions, such as 100, and then get students to answer as many as possible in 5 or 10 minutes. Have a prize for the one with the highest point score (awarding accuracy and speed).
