All fractions like x/9 or xx/99 or xxx/999 have x, xx, or xxx as a repeating decimal. 3/9 is therefore the answer.

It has to be 3/9 since all the others have no repeating decimals, just a single digit.
If you are not sure what a repeating decimal is do the division of 3/9 and look at the answer you get to learn it.

I think you need a new way to look at Fractions.
A Fraction is an indicated Division proplem To change a Fraction to a Decimal. you Divide the Demoninator into the Numerator. Fractions are easy once you understand that basic principle.
Only 3 Divided by 9 will produce a Repeating Decimal in that group.

Well, 6/3 = 2.0, a terminating decimal
1/2 = 0.5, also a terminating decimal
2/5 = 0.4, also a terminating decimal
So 3/9 = 1/3 = 0.33333... is the answer.
Suppose we have a fraction in lowest terms.
If the only prime factors of the denominator
are 2 and(or) 5 the decimal expansion of
this fraction will be terminating. Why?
Because, by multiplying top and bottom of
the fraction by a suitable factor we can
make the denominator a power of 10.

3/9. However, a weird quirk about mathematics is this:
9 x 1/9 = 9 x 0.11111_ = 0.9999999
or
9 x 1/9 = 9/9 = 1

I had fun with my algebra teacher with this one
