FDP equivalence converts between fractions, decimals and percentages, recognising common equivalences and ordering mixed forms. It's a core topic in GCSE and iGCSE Maths with Edexcel and the other major boards. This free interactive eClassroom course walks through each step with worked examples and instant-feedback questions, so you can practise until it's secure.
How you do it
To go from a fraction to a decimal, divide top by bottom. To go from a decimal to a percentage, multiply by 100. To go from a percentage to a fraction, write it over 100 and simplify. Learn the common ones by heart so you can convert without thinking.
Before you start
It draws heavily on fractions and place value. It reappears throughout percentages and probability.
What you learn
Fractions, decimals and percentages are three ways of writing the same value. Converting between them quickly is one of the most useful skills on the paper. To compare a mix of fractions, decimals and percentages, convert them all to the same form — decimals are usually easiest. The course works through decimals and percentages, fractions to decimals and percentages and comparing and ordering. Every section has instant-feedback practice questions matched to Edexcel iGCSE 4MA1 and the other major GCSE boards, and the course finishes with full exam-style questions you mark yourself.
