Question

If you Subtract 1 by 2 from a number and multiply the result by 1 by 2,you get 1 by 8.What is the number?

Answer 1

Answer:

3/4

Step-by-step explanation:

Let the number be x

(x-1/2)×1/2=1/8

x-1/2=1/8÷1/2

x-1/2=1/8×2

x-1/2=1/4

x=1/4+1/2

x=1+2/4

x=3/4

Answer 2

Answer:

3/4

Step-by-step explanation:

Let the number be x.

According to the question,

→ (x – 1/2) × ½ = 1/8

=> x/2 – ¼ = 1/8

=> x/2 = 1/8 + ¼

=> x/2 = 1/8 + 2/8

=> x/2 = (1+ 2)/8

=> x/2 = 3/8

=> x = (3/8) × 2

=> x = ¾
