Answer 2

$\underline{\huge\text{Answer:}}$

Let , $x = 15.7\overline{12}$ ..... (1)

By multiplying 10 on both sides of equation (1) , we get —

$10x = 157.121212$

$= > 10x = 157 + 0.121212$

$= > 10x = 157 + \frac{12}{99}$

$= > 10x = \frac{157 \times 99 + 35}{99}$

$= > 10x = \frac{15543 + 35}{99}$

$= > 10x = \frac{15578}{99}$

$= > x = \frac{15578}{990}$

Therefore , $15.7\overline{12}$ can be represented in thr form :-

$\frac{p}{q} = \frac{15578}{990}$
