Worksheet Overview

QUESTION 1 of 10

Percentage multipliers are useful as a quick way to work out percentage increases and decreases.

 

Percentage Increases

Multiply by 1 + percentage as a decimal

 

A 5% increase will multiply the original amount by 1.05

 

Percentage decreases

Multiply by 1 - percentage as a decimal

 

A 5% decrease will multiply the original amount by 0.95

 

Example 1

A table costs £250 plus 20% VAT.  What does it cost with VAT included?

 

Answer

We must increase £250 by 20%. 

The multiplier is 1 + 0.20 = 1.20 or 1.2

Answer is £250 x 1.2 = £300

 

Example 2

A tennis racket costs £90 but there is then a discount of 15%.  What does it cost after the discount is applied?

 

Answer

We must decrease £90 by 15%. 

The multiplier is 1 - 0.15 = 0.85

Answer is £90 x 0.85 = £76.50
