Equivalent fractions, percentages and ratios
A value is shown, such as 52/80, with four choices written as percentages, ratios, plain numbers and 'out of' statements. The student taps every choice that is equal to it.
The decoys are close misreadings, such as a percentage a hundred times too big, so each choice has to be converted rather than eyeballed.
Numbers&Me is free. Sign up to practise more, or set it as homework in under a minute, and it marks itself.
