You have learned to write a fraction as a sum of unit fractions. For example, $$\frac{4}{5}$$ = $$\frac{1}{5}$$ + $$\frac{1}{5}$$ + $$\frac{1}{5}$$ + $$\frac{1}{5}$$.
You can also write a fraction as a multiple of a unit fraction.

Build It
Use an equation to write $$\frac{4}{5}$$ as a multiple of a unit fraction.
One Way:
Use fraction tiles.
Model $$\frac{4}{5}$$ using fraction tiles. Draw your result below.
How many $$\frac{1}{5}$$-tiles did you use?

Another Way:
You know that $$\frac{4}{5}$$ = $$\frac{1}{5}$$ + $$\frac{1}{5}$$ + $$\frac{1}{5}$$ + $$\frac{1}{5}$$
How many times is added to equal $$\frac{4}{5}$$?
So, $$\frac{4}{5}$$ = ________________ Ă— $$\frac{1}{5}$$.
$$\frac{4}{5}$$ = 4 Ă— $$\frac{1}{5}$$.

Explanation:
$$\frac{4}{5}$$ as a multiple of a unit fraction = ??
1. Use fraction tiles:

You know that $$\frac{4}{5}$$ = $$\frac{1}{5}$$ + $$\frac{1}{5}$$ + $$\frac{1}{5}$$ + $$\frac{1}{5}$$
=> 4 timesÂ $$\frac{1}{5}$$ is added to equal $$\frac{4}{5}$$.

You know that 6 is a multiple of 2. Any multiples of 6, such as 12, 18, and 24, are also multiples of 2. The same is true for fractions. A multiple of a fraction can also be written as a multiple of a unit fraction.

Try It
Use an equation to write 2 Ă— $$\frac{4}{5}$$ as a multiple of a unit fraction.

Use repeated addition to write 2 Ă— $$\frac{4}{5}$$ as $$\frac{4}{5}$$ + $$\frac{4}{5}$$.
$$\frac{4}{5}$$ + $$\frac{4}{5}$$ = $$\frac{8}{5}$$ Add like fractions.
Model $$\frac{8}{5}$$ using fraction tiles. Draw your result below.

Equation showing that $$\frac{8}{5}$$ is a multiple of the unit fraction $$\frac{1}{5}$$ is
2 Ă— $$\frac{4}{5}$$ = 8 Ă— $$\frac{1}{5}$$.

Explanation:
2 Ă— $$\frac{4}{5}$$ as a multiple of a unit fraction = ??
1. Use fraction tiles:

2 Ă— $$\frac{4}{5}$$ = $$\frac{4}{5}$$ + $$\frac{4}{5}$$ = $$\frac{8}{5}$$

2 Ă— $$\frac{4}{5}$$ = $$\frac{4}{5}$$ + $$\frac{4}{5}$$.
