$0.1\overline{8}$

Step 1

Set up an equation with $0.1\overline{8}$ .

$x = 0.1\overline{8}$

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 $x = 0.1\overline{8}$ by $10$ to create the first equation.

$10 x = 1.\overline{8}$

Step 4

Multiply both sides of $x = 0.1\overline{8}$ by $100$ to create the second equation.

$100 x = 18.\overline{8}$

Step 5

Subtract $10 x = 1.\overline{8}$ from $100 x = 18.\overline{8}$ to remove the repeating part.

$90 x = 17$
