Mixed Numbers and Improper Fractions

Numbers come in many shapes and sizes. We are going to focus on two types.

Mixed Numbers - a whole number and a proper fraction (i.e., Mixed numbers and improper fractions img 1 )

Improper Fractions - a fraction where the top is larger than the bottom. (i.e., Mixed numbers and improper fractions img 2 )

A mixed number can be changed to an improper fraction. AND an improper fraction can be changed to a mixed number.

Let's look at the steps:

Example #1: Mixed numbers and improper fractions img 4

Mixed numbers and improper fractions img 3

So Mixed numbers and improper fractions img 5.

So how might we be able to do this without the picture every time?

There were 3 wholes with 8 pieces each. So we have 3 x 8 pieces. Then there were an addition 5 pieces that we need to add on. So the numerator becomes 3 x 8 + 5. The denominator stays the same.
