The vulgar fraction of 0 .39 39 is ?

Answer: Option D

The given expression can be written in this form also
N = $$\text{ 0}\text{.39}\overline{\text{39}}$$ ..... (i)
Multiply equation (i) with 100 on both sides.
100N = $$\text{39}\text{.}\overline{\text{39}}$$ ..... (ii)
Subtracting equation (i) from (ii) we get,
⇒ 100N - N = $$\text{39}\overline{\text{.39}}$$  - $$\text{0}\overline{\text{.39}}$$
⇒ 99N = 39
⇒ N = $$\frac{39}{99}$$ = $$\frac{13}{33}$$
