Select the correct answer.

What is the fractional form of [tex]$0.\overline{02}$[/tex]?

A. [tex]\frac{2}{99}[/tex]
B. [tex]\frac{1}{11}[/tex]
C. [tex]\frac{2}{100}[/tex]
D. [tex]\frac{1}{12}[/tex]



Answer :

To find the fractional form of the repeating decimal [tex]\(0.\overline{02}\)[/tex], let's denote this repeating decimal by [tex]\(x\)[/tex].

[tex]\[x = 0.02020202\ldots\][/tex]

If we multiply both sides of this equation by 100 (since the repeating segment consists of 2 digits), we get:

[tex]\[100x = 2.02020202\ldots\][/tex]

Next, we subtract the original [tex]\(x\)[/tex] from this new equation:

[tex]\[100x - x = 2.02020202\ldots - 0.02020202\ldots\][/tex]

Simplifying, we have:

[tex]\[99x = 2\][/tex]

Now, we solve for [tex]\(x\)[/tex] by dividing both sides of the equation by 99:

[tex]\[x = \frac{2}{99}\][/tex]

Thus, the repeating decimal [tex]\(0.\overline{02}\)[/tex] is represented as the fraction [tex]\(\frac{2}{99}\)[/tex].

Therefore, the correct answer is:
A. [tex]\(\frac{2}{99}\)[/tex]
