- 0.58 ¯ 3

$- 0.58\overline{3}$

Step 1

Set up an equation with

0.58 ¯ 3

$0.58\overline{3}$ .

x = 0.58 ¯ 3

$x = 0.58\overline{3}$

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 = 0.58 ¯ 3

$x = 0.58\overline{3}$ by

100

$100$ to create the first equation.

100 x = 58. ¯ 3

$100 x = 58.\overline{3}$

Step 4

Multiply both sides of

x = 0.58 ¯ 3

$x = 0.58\overline{3}$ by

1000

$1000$ to create the second equation.

1000 x = 583. ¯ 3

$1000 x = 583.\overline{3}$

Step 5

Subtract

100 x = 58. ¯ 3

$100 x = 58.\overline{3}$ from

1000 x = 583. ¯ 3

$1000 x = 583.\overline{3}$ to remove the repeating part.

900 x = 525

$900 x = 525$

Step 6

Divide each term in

900 x = 525

$900 x = 525$ by

900

$900$ and simplify.

Step 6.1

Divide each term in

900 x = 525

$900 x = 525$ by

900

$900$ .

\frac{900 x}{900} = \frac{525}{900}

$\frac{900 x}{900} = \frac{525}{900}$

Step 6.3.1.2.1

Factor

$75$ out of

$900$ .

$x = \frac{75 \cdot 7}{75 \cdot 12}$

Step 6.3.1.2.2

Cancel the common factor.

$x = \frac{75 \cdot 7}{75 \cdot 12}$

Step 6.3.1.2.3

Rewrite the expression.

$x = \frac{7}{12}$

Step 7

Write as a mixed number by taking the whole number part along with the solution to the equation.

$- 0 \frac{7}{12}$

Step 8

Convert

$0 \frac{7}{12}$ to an improper fraction.

Step 8.1

A mixed number is an addition of its whole and fractional parts.

$- (0 + \frac{7}{12})$

Step 8.2

Add

$0$ and

$\frac{7}{12}$ .

$- \frac{7}{12}$
