# Rearrange Algebraic Formulae

In this worksheet, students will learn how to rearrange formulae to find the given letter (subject) of the formula. Key stage:  KS 3

Curriculum topic:   Algebra

Curriculum subtopic:   Simplify Algebraic Expressions to Maintain Equivalence

Difficulty level: #### Worksheet Overview

Often we will be presented with a formula that will need to be manipulated in order to be useful to us.

We may have to rearrange the formula, making a different letter the subject.

Use the rules of equations (i.e. do the same to both sides) to achieve this.

Example:

The formula for finding a temperature in degrees centigrade from one in Fahrenheit is shown below.

Rearrange the formula to make F the subject.

Our aim is to get F on its own on the left-hand side. And we're there!!

Now it's over to you.
