As before, a selection of ‘minimally different’ questions on sharing in a ratio (including answers!).
The first sheet is on ratio questions where 1 part is given – the second is on ratio questions where the different is question.
N.B. Success with these questions does NOT make a student confident/competent at all ‘sharing in a ratio type’ questions! It is fundamental that they are then given the opportunity to practise selecting the question method based on the question type (some problems from http://www.ssddproblems.com would probably be ideal at this stage). This is only for introducing a concept to a class.
As ever, I hope you find these useful – feedback would be wonderful.
