**fraction & use a forward slash to đầu vào fractions i.e., 12/3**. An example of a negative mixed fraction:

**-5 1/2**.

**Because slash is both signs for fraction line and division, use a colon (:) as the operator of division fractions i.e., 1/2 : 1/3**.

**Decimals (decimal numbers) enter with a decimal point .**và they are automatically converted to lớn fractions - i.e.

**1.45**.
