Introduction

Three languages, one number

In Maths, a portion of something can be written three ways: fraction, decimal, or percentage. They always mean exactly the same thing.

About the FDP Equivalences lesson

A fraction, a decimal and a percentage can all describe the same part of a whole. In this lesson your child taps to change one form and watches the other two update at the same time, so the link between them is something they see, not just a rule.

The lesson then teaches the equivalences that come up most often in 11+ papers, and a two-step method for any fraction: divide the top by the bottom, then multiply by 100. A recall exercise helps the common ones become instant.

Worked example

Question: Write 3/4 as a decimal and as a percentage.

Answer: Divide 3 by 4 to get 0.75. Multiply by 100 to get 75%. A quick check: one quarter is 25%, so three quarters is three times that, which is 75%.

Who it suits

This lesson suits children aged 8 to 11 who can convert one form but lose time converting between all three, and those preparing for a timed Maths paper.
