This worksheet gives a scaffolded approach to solving ratio problems involving converting two two-part ratios to a single three-part ratio.
Section A leads learners through a structured process to find a common multiple which will give the final three-part ratio.
Section B provides more problems similar to Section A but with blank tables and no scaffolding.
Section C then introduces the problem of the ratio of distances between four points on a line. A diagram and structured process are provided for each question.
Section D then provides some worded contextual problems which will require the processes used in the earlier sections.
