**Fractions and decimals** in the English language are used to indicate partial amounts of something. Apart from being used in mathematics, fractions and decimals also have applications in daily life - for example, in recipes (e.g. ½ litre milk).

Translation

Take **1/4** cup of milk.

*1/4* (*one quarter*) indicates the necessary partial amount of milk.

## Fractions

**Rule 1:** We use both *cardinal* and *ordinal* numbers to create fractions. The **numerator** (*the numeral above the line*) is always a **cardinal** number while the **denominator** (*the numeral below the line*) is always an **ordinal** number.

Here's how to write and spell fractions in English:

1/3 | one third | 1/10 | one tenth |

1/5 | one fifth | 1/20 | one twentieth |

1/6 | one sixth | 1/100 | one hundredth |

1/8 | one eighth | 1/1000 | one thousandth |

**Note:** There are also exceptions which you should memorize by heart.

1/2 | one half |

1/4 | one quarter |

**Rule 2:** When a *numerater* is **greater than one**, we use the *denominator* in **plural** by adding an *s*.

2/3 | two thirds |
---|---|

3/4 | three quarters |

5/8 | five eighths |

4/10 | four tenths |

7/12 | seven twelfths |

**Rule 3:** Fractions can be written in two different ways. You can either put a slash between numerals (e.g, 2/5) or you can write the numerals on top of each other and are separated by a horizontal line. The latter option is mostly used in mathematics.

## Decimal Numbers

**Rule 3: **We write **decimal numbers** with a decimal point. The digits *after* the decimal point are said *separately*.

three point one four one five nine

## Singular and Plural with Fractions and Decimals

**Rule 4:** We use the contruction **of a + singuar noun **if we want to say exactly what the *fraction* or *decimal* refers to and the **value is less than one**.

Native

Translation

3/4 mi

three quarthers *of a mile*

2/3 cup

two thirds *of a cup*

**Note:** The only exception is **1/2**. We use it without the word *of*.

Native

Translation

1/2 liter

half *a liter*

**Rule 5:** The *numeral* needs to be followed **directly by a plural noun** if the value of the *fraction* or *decimal* is **greater than one**.

- one and a third kilometers
- three and a half hours
- two and a quarter cups
