Question

If you Subtract 1/2 from a Number and Multiply the result by 1/2, you get 1/8. What os the number?.​

Answer 1

Let the number to be identified be x

As per the given condition

If we subtract 1/2 from a number and multiply the result by 1/2, we get 1/8.

So the equation becomes

(1/2)(x – 1/2) = (1/8)

=(x – 1/2) = (1/4)

=4x – 2 = 1

=4x = 3

Hence x = 3/4

Therefore 3/4 is the number from which if we subtract 1/2 from a number and multiply the result by 1/2, we get 1/8.

Answer 2

Answer:

Let the no. be x

(x-1/2) × 1/2 = 1/8

=> 2x-1/2 × 1/2 = 1/8

=> 2x-1/4 = 1/8

=> 8(2x-1) = 4

=> 16x-8 = 4

=> 16x = 4+8

=> x = 12/16

=> x = 3/4. ans......
