## Proportion

Here's a reminder of the different ways of representing quantities or proportions and what each means:

### Decimals

A decimal is a way of writing a number that is not whole.

### Percentage

Percent means 'per 100' and it's shown using the symbol %.

### Fractions

A fraction is a part of a whole. There are two numbers to every fraction: the top number of the fraction is called the numerator. The bottom number is called the denominator.
