Question

If we subtract 1/2 from a number and multiply the result by 1/2, we get 3/8. what is the number?

Answer 1

Answer:

let the no be X

Step-by-step explanation:

[X - 1/2] x 1/2 =3/8

1/2 goes to RHS

X -1/2 =3/8 x 2/1

X - 1/2 =6/8

1/2 goes to RHS

X = 6/8 - 1/2

X = 6/8 - 4/8

X = 2/8

X =1/4

Answer 2

Answer:

let the no. be x .

so,

(x - 1/2) × 1/2 = 3/8

x - 1/2 = 3/8 × 2

x - 1/2 = 3/4

x = 3/4 + 1/2

x = 5/4
