$0.0\overline{3}$

Step 1

Set up an equation with

$0.0\overline{3}$ .

$x = 0.0\overline{3}$

Step 2

Create two equations where the only numbers to the right of the decimal place are the repeating part.

Step 3

Multiply both sides of

$x = 0.0\overline{3}$ by

$10$ to create the first equation.

$10 x = 0.\overline{3}$

Step 4

Multiply both sides of

$x = 0.0\overline{3}$ by

$100$ to create the second equation.

$100 x = 3.\overline{3}$

Step 5

Subtract

$10 x = 0.\overline{3}$ from

$100 x = 3.\overline{3}$ to remove the repeating part.

$90 x = 3$
