This resource is aimed at helping students answer a new style of GCSE question, where the initial ratio of a mixture (typically a drink) is given, a fraction of the total amount is removed and/or an amount is added and students then have to find a ratio, fraction or percentage from the final situation.
The resource is for KS4 students taking the Higher paper.
The resource consists of a lesson presentation with two examples. Students are then given three similar problems to answer and the worked solutions to these are included.
