Decompose Fractions
To decompose a given fraction into a sum of two, three, or four fractions, we first decompose it into unit fractions.
For example:
Let's decompose the fraction
5 6
into a sum of three fractions.
In order to do so, first let's decompose the given fraction into unit fractions.
This model represents a whole divided into 6 equal parts. Here, each part represents the unit fraction
1 6
.
The 5 shaded parts represent the fraction
5 6
.
Now, write
5 6
as the sum of unit fractions.

=
