→  Given Question :  if you subtract 1/2 from a number and multiply the result by 1/2 , you get 1/8. what is the number? ​

Step-by-step explanation:

→ solution :  Let the required number be x

→ condition 1 : x- 1 /2            

   

→ condition 2 : 1 / 2 × ( x - 1/2)

→ condition 3 :  1 / 2 × ( x - 1 / 2 ) = 1 / 8

→ 1 / 8 × (x - 1 / 2 ) = 1 / 8 × 8

→ [ ∵ Multiplying both sides by the L.C.M of 2 and 8 that is  8 ]

→ 4 × ( x - 1/2 ) = 1      

→ 4x -1 /2 × 4 = 1  ( ∵ solving bracket )

→ 4x  - 2 = 1

→ 4x - 2 + 2 = 1 +2   (  ∵  Adding 2 to both sides )

→ 4x  =  3

→ 4x ÷ 4 = 3 ÷ 4      ( ∵ dividing both sides by 4 )

→ Thus the required numbers is 3 /4

→ Thank you
