4. ¯ 6

$4.\overline{6}$

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. ¯ 6

$0.\overline{6}$ .

x = 0. ¯ 6

$x = 0.\overline{6}$

Step 3

Multiply both sides of

x = 0. ¯ 6

$x = 0.\overline{6}$ by

10

$10$ to create the second equation.

10 x = 6. ¯ 6

$10 x = 6.\overline{6}$

Step 4

Subtract

x = 0. ¯ 6

$x = 0.\overline{6}$ from

10 x = 6. ¯ 6

$10 x = 6.\overline{6}$ to remove the repeating part.
