Answer 2

Step-by-step explanation:

let the no. x,

therefore,

$= > (x - \frac{1}{2} ) \times \frac{1}{2} = \frac{1}{8} \\ = > (\frac{x}{1} - \frac{1}{2} ) \times \frac{1}{2} = \frac{1}{8} \\ = > ( \frac{2x}{2} - \frac{1}{2} ) \times \frac{1}{2} = \frac{1}{8} \\ = > \frac{2x - 1}{2} \times \frac{1}{2} = \frac{1}{8} \\ = > \frac{2x - 1}{4} = \frac{1}{8} \\ = > 8(2x - 1) = 4 \\ = > 16x - 8 = 4 \\ = > 16x = 4 + 8 \\ = > 16x = 12 \\ = > x = \frac{12}{16} \\ = > \frac{3}{4}$

Hence the answer is 3/4
