Worksheet Overview

QUESTION 1 of 10

If you rearrange a formula, you change the variable which is its subject.

 

In A = b × h (the formula for area of a rectangle), A is the subject, because it is on its own on one side of the equals sign.

 

You can change the subject of the formula by using inverse operations.

 

 

Have a look at an example below.

 

e.g. v = u + at (formula for final velocity). Make a the subject of the formula.

 

We need to inverse the operations.

Let's first move u to the other side by subtracting it from both sides: v - u = at

at means a × t, so to reverse this, we need to divide both sides by t: (v - u) ÷ t = a

Now a is the subject of the formula, as it is on its own on one side of the equation.

 

See how (v - u) is in brackets?

This is because we want to divide the entire left-hand side by t, not just v or u.

 

 

 

Now it's your turn to inverse those operations!

 

In this activity, we are going to rearrange formulae to make different terms the subject using inverse operations.
