Practise GCSE Maths ratio and proportion topics including simplifying ratios, sharing, direct and inverse proportion, percentage change, best value, scaling and compound measures.
Ratio and proportion are used to compare quantities and understand how values scale together.
These topics appear often in real-life GCSE Maths problems involving recipes, money, speed, density, maps, percentages and rates of change.
Understand what ratio means and compare quantities using ratio notation.
Simplify ratios into their lowest form just like simplifying fractions.
Divide amounts into parts using a given ratio.
Solve problems where two quantities increase or decrease together in a fixed ratio.
Solve problems where one quantity increases while the other decreases.
Work out percentage increase and decrease in real exam-style problems.
Use multipliers to model repeated percentage increase or decrease over time.
Compare prices and quantities to decide which option gives the best value.
Convert between currencies using exchange rates and proportional reasoning.
Scale recipes and quantities up or down using ratio and proportion.
Use the relationship between speed, distance and time to solve problems.
Use the density, mass and volume formula triangle in practical calculations.
Work with measures like speed and density that combine different units.
GCSE Maths Ratio and Proportion includes simplifying ratios, sharing in a ratio, direct and inverse proportion, percentage change, growth and decay, best value, currency conversion, scaling, speed, density and compound measures.
You should be confident with fractions, decimals, percentages and basic algebra before moving into ratio and proportion.
They are common because they test real-life mathematical reasoning, including scaling, comparing, converting and working with rates.
