If you subtract 1/2 from a number and multiply the result by 1/2, you get 1/8. What is the number?
Let the number be x
Substraction of 1/2 from x = x-1/2
Then multiplication of the result obtained by 1/2 =( x-1/2)1/2
Result got at last = 1/8
Then find the number?????
(x - 1/2) 1/2 =1/8
x - 1/2 =1/8 ×2
x-1/2 = 1/4
Do fraction of x - 1/2
2x-1/2 =1/4
Criss cross method
LHS goes to RHS and RHS goes to LHS
4(2x -1) = 2
8x - 4 = 2
8x = 2+4
8x = 6
Then
x = 6/8
x = 3/4
