# Rationalise - Turn into fraction

Rations can be shared half each (rations can be fractions).

**Examples**

1.5 is rational because = `3/2`

0.333 is rational because = `1/3`

`pi` is not rational (irrational) because it can’t be turned into a fraction.

3.14155……….

**NOTE:**

`22/7` is bigger than `pi`. It’s close but not accurate.

`sqrt2` is irrational because it can’t be turned into a fraction.
