Question

If you subtract 1/8 from a number and multiply the result by 1/4,you get 1/16. what is the number?

Answer 1

let the number be "x"

now,according to question ,

1/ 4 ( x - 1 / 8 )= 1 / 16

( 8x - 1 ) / 8 = 4 / 16

8x - 1 = 8 / 4

8x - 1 = 2

8x = 2 + 1

8x = 3

x = 3 / 8

Answer 2

$\large{\boxed{\bold{Answer:}}}$


Let the number be x,

$(x - \frac{1}{8}) \times \frac{1}{4} = \frac{1}{6} \\ \\ = > 8x - \frac{1}{8} = \frac{4}{16} \\ \\ = > \frac{(8x - 1)}{8} = \frac{1}{4} \\ \\ = > 8x - 1 = 2 \\ \\ = > 8x = 2 + 1 \\ \\ = > 8x = 3 \\ \\ = > x = \frac{3}{8}$

Hence the Number required is 3/8
