Division and multiplication can be used to solve ratio problems.
A table can be used to collect the information needed to solve the problem.
The representation helps to identify the calculations needed to solve the problem.

Knowing how to create a table or bar model to represent a context presented in words.

Discuss the context to identify the parts and the wholes in order to build an appropriate representation of the context.

Ratio - A ratio shows the relative sizes of 2 or more values and allows you to compare a part with another part in a whole
For every - For every allows you to talk about the relative sizes of the values e.g. for every 2 squares there is 1 triangle
