Basic Math Examples

$1.\overline{2}$

Step 1

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

Step 2

Set up an equation with $0.\overline{2}$ .

$x = 0.\overline{2}$

Step 3

Multiply both sides of $x = 0.\overline{2}$ by $10$ to create the second equation.

$10 x = 2.\overline{2}$

Step 4

Subtract $x = 0.\overline{2}$ from $10 x = 2.\overline{2}$ to remove the repeating part.

$9 x = 2$
