Ratios, Proportion and Rates of Change

By this stage of your GCSE maths revision you’re bound to be tired. Don’t worry, there is light at the end of the tunnel! This last topic of ratios calls on a lot of the knowledge you already know so you’re almost at the finish line. This areas consists of:

Ratios: Expressing fractions as ratios should be easy for you now! You also need to relate ratios to fractions and linear equations. Understanding and relating proportion to ratios will also be studied here
Measurement: There are numerous units of measurement so you need to be able to translate these interchangeably. This could be relating measurements such as area, length, mass
Rates of Change: The difficult part of this section is being able to solve and interpret rates of change in terms of numbers, algebraic equations and graphs. An example of this interpreting answers in growth and decay problems
