The overbar indicates the digit repeats forever. It is worth remembering that

[tex]0.\overline{x}=\dfrac{x}{9}\qquad\text{x = any single digit}[/tex]

Your number is 3/9 = 1/3

Answer:

0.333.. repeating = [tex]\frac{1}{3}[/tex]

Step-by-step explanation:

The given number is 0.333...

The bar represents 3 continues forever.

Let's find the rational number that represents 0.333...

The rational number is in the form of [tex]\frac{p}{q}[/tex], where q ≠ 0.

Let x = 0.333...

Let's multiply both sides by 10, we get

10x = 3.33...

Now let's subtract x from 10x

10x - x  = 3.33... - 0.333..

9x = 3

Now let's divide both sides by 9, we get

[tex]\frac{9x}{9} = \frac{3}{9}[/tex]

x = [tex]\frac{3}{9}[/tex]

When we simplify the above, we get

x  = [tex]\frac{1}{3}[/tex]

So the rational number [tex]\frac{1}{3}[/tex] represents 0.333....
