# Difference between revisions of "Mixed number"

A mixed number is a number that contains an integer and a proper fraction. An example of a mixed number is $9 \frac34$. All mixed numbers can be written as improper fractions (and vice versa).

## Operations with Mixed Numbers

When adding or subtracting mixed numbers, we generally add or subtract each part -- add/subtract fraction (sometimes with conversion to common denominator) and add/subtract whole numbers. Sometimes, we may need to regroup fractions or "borrow" from whole numbers -- much like regrouping or borrowing when adding multi-digit numbers.

Alternatively, we can convert to improper fractions and add/subtract like regular fractions.

### Multiplication and Division

When multiplying or dividing mixed numbers, we can convert to improper fractions and proceed as usual.
