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).

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.

2/3two 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.
