Question

If you subtract 1/2 from a number and multiply he result by 1/2 , you get i/8 . what is the number

Answer 1

Step-by-step explanation:

let the no. be 'X'

therefore,

X-1/2=(1/8)÷(1/2)

=(1/8) ×(2/1) [Reciprocal]

=1/4

X-1/2=1/4×1/2

X-1/2=1/8

X=1/8+1/2 [Lcm=8]

X=1+4/ 8

X=5/8

Hence the required no. =5/8
