A fraction tells us how many parts of a certain size there are. Every fraction has a numerator and a denominator.

The numerator is the top number in a fraction and tells us how many equal parts there are.

The denominator is the bottom number and tells us the size and the total number of equal parts needed to make a whole.

In the fraction above, the numerator is $1$ and the denominator is $4$. So, there is one-fourth slice of pizza or $1$ of $4$ slices needed to make a whole pizza.

## Writing Fractions

A fraction tells us how many parts of a certain size there are. The parts can be portions of a single item or portions of a group.

There are two-third slices of pizza or $2$ of $3$ slices needed to make a whole pizza.

The numerator is the top number in a fraction and tells us how many equal parts there are.

The denominator is the bottom number and tells us the size and the total number of equal parts needed to make a whole.

As the size of the denominator

**increases**, the size of the parts**decreases**.### Smaller Denominator

### Bigger Denominator

Since the number of parts needed to make a whole will always be nonzero, the denominator can never be 0.$0n =undefined$

### Types of Fractions

Type | Rule | Example |

Proper Fraction | top $<$ bottom | $32 $ |

Improper Fraction | top $>$ bottom | $23 $ |

Mixed Number | whole number $+$ fraction | $132 $ |
