Question

if you subtract 1/2 from a number and multiply the result by 1/2 you get 1/8. what is the number?

Answer 1

let the number be x,

ATQ,

$[x- \frac{1}{2}]$×$\frac{1}{2} = \frac{1}{8}$


$[ \frac{2x-1}{2}]$ = $\frac{2}{8}$


$\frac{2x-1}{2} = \frac{1}{4}$

Cross multiply,

4(2x-1) = 1*2

8x - 4 =2

8x = 2+4

8x = 6

x =6/8 =3/4


Now,

the number required here is 3/4 


i hope this will help you

Answer 2

Answer:

3/4

Step-by-step explanation:

f you subtract 1/2 from a number and multiply the result by 1/2 you get 1/8. what is the number?

Let number be x

Since we are given subtract 1/2 from a number and multiply the result by 1/2 you get 1/8

$[x- \frac{1}{2}]*\frac{1}{2} =  \frac{1}{8}$

$[ \frac{2x-1}{2}] =\frac{2}{8}$

$\frac{2x-1}{2} =  \frac{1}{4}$

Cross multiply,

4(2x-1) = 1*2

8x - 4 =2

8x = 2+4

8x = 6

x =6/8 =3/4

Hence , the number required here is 3/4
