Answer 2

$let \: x = 3.12 \overline{7}$

Therefore,

$100x = 312. \overline{7}$

$\implies 1000x = 3127. \overline{7}$

$\implies 1000x - 100x = 3127. \overline{7} - 312. \overline{7}$

$\implies 900x = 2815$

$\implies x = \frac{2815}{900}$

$\implies x = \frac{563}{180}$

Answer:-

$x = \frac{563}{180}$
