homesitemapfractionsconverting improper to mixed fractions
Mixed fractions can be converted to improper fractions.

• A mixed fraction has a whole number and a fraction.
• An improper fraction (or top-heavy fraction) is a fraction where the top number is greater than (or equal to) the bottom number.

## Question

Convert the mixed fraction below to an improper fraction.
Don't forget: A mixed fraction has a 'whole number' part (2 in our example) and a 'fraction' part (½). The top number of the fraction (1) is called the numerator. The bottom number of the fraction (2) is called the denominator.

## 1

Multiply the whole number (2) by the denominator of the fraction (2).

2 × 2 = 4

## 2

Take this answer (4) and add the numerator (1) of the fraction part of the mixed fraction.

4 + 1 = 5

## 3

Make this the numerator of the improper fraction.

## 4

Take the denominator from the fraction part of the mixed fraction (2) and make this the denominator of the improper fraction.

## 5

Simplify the fraction if possible. (The fraction in our example is already as simple as possible).

5/2 (five-halves) is 2 1/2 (two and a half) written as a mixed fraction.

## What Is a Fraction?

A fraction is a part of a whole number. Fractions consist of a numerator and a denominator There are three different types of fractions:

## Mixed Fractions

An improper fraction is a type of fraction, where the numerator is greater than or equal to the denominator.

## Improper or "Top-Heavy" Fractions

An improper fraction is a type of fraction, where the numerator is greater than or equal to the denominator.

Improper fractions are sometimes called "top-heavy" fractions, because the top of the fraction is bigger than the bottom.
