### The parts of a fraction

A fraction is a number.

Every time you read or write a division, you are reading or writing a fraction. £$14 : 6$£ is a division. Also, you can write it horizontally £$14/6$£ or vertically £$\dfrac{14}{6}$£.

Fractions have three parts: the line of fraction, the top number and the bottom number.

The number written above the line of fraction is the numerator: it tells us the number of parts we have.

The number written below the line of fraction is the denominator: it tells us the number of parts the whole has been divided into.

The line of fraction means "divided by".
