Turning decimals into fractions and percentages or vice versa requires **recalling the common decimal numbers and the ****place value of numbers. **

Here is how to turn a fraction to its decimal or percentage equivalent:

- remember the 10 common decimal numbers and their fractions and percentages equivalents, and
- apply the rule of multiplying top and bottom number by 10, 100, 1000,

## Turn 10 common decimals to fractions or percentages by recall

Decimal | Fraction | Percentage |
---|---|---|

0.1 | ¹/10 | 10% |

0.125 | ⅛ | 12.5% |

0.2 | ⅕ | 20% |

0.25 | ¼ | 25% |

33.3… | ⅓ | 33⅓% |

0.4 | ⅖ | 40% |

0.5 | ⅔ | 66⅔% |

0.6 | ½ | 50% |

66.6… | ⅗ | 60% |

0.75 | ¾ | 75% |

These 10 decimals and their equivalent fractions (and percentages) are often used in primary and secondary schools maths tests and exams.

Memorising the decimals will make it really quick and easy to solve related mathematics problems as/when they appear.

**Practice Exercise 1**: Turn the decimals into fractions by recall:

- 0.1 =
- 0.25 =

Recalling the 10 decimal numbers will make it easier to change them to fractions and decimals or the other way around.

## Turn Decimals to Fractions by working out

To change a decimal number to its equivalent fraction follow these steps:

- Write down the decimal over one (i.e. decimal/1)
- Multiply both top and bottom by 10, 100, 1000, etc
- Simplify

**Example: Convert 0.6 to the fraction**

In this example, we’ll multiply 10 on the top and bottom due to one decimal place in 0.6 – one decimal place. If it is two decimal places, x 100, three decimal places x 1000, etc…

**Practice Exercise 2:** Change the following decimals to fractions. Give answers in simplest fractions.

1. 0.7 =

2. 0.04 =
