## Definition

A **percentage** is a convenient way of expressing (usually) a fraction as an easily-grasped number, by multiplying it by $100$ and appending the symbol $\%$ which means **per cent**.

As conventionally understood, the number being rendered as a **percentage** is between $0$ and $1$, thus determining the range of a **percentage** to be $0 \%$ to $100 \%$.

However in many contexts that range is frequently extended (in particular, in the field of rhetoric):

*I want every member of this team to give one hundred and ten percent.*

## Examples

### Example: $50 \%$

$\dfrac 1 2$ as expressed in **percentage form** as:

- $\dfrac 1 2 \times 100 = 50 \%$

### Example: $120 \%$

$1.2$ can be expressed in **percentage form** as:

- $1.2 \times 100 = 120 \%$

## Linguistic Note

**Centum** is Latin for $100$. So **per cent** merely means **per hundred**.

Thus, for example $68 \%$ can be read and interpreted as **sixty eight per hundred**.

That is, sixty eight out of $100$, or $\dfrac {68} {100}$.
