Question

plz send correct answer (if you subtract 1/2 from a number and multiply by 1/2 you get 1/8. what is the number?)​

Answer 1

Answer:

The number is 3/4 .

Explanation:

Let the number be x .

According to the question,

$(x - \frac{1}{2} ) \times \frac{1}{2} = \frac{1}{8} \\ = > ( \frac{2x - 1}{2} ) \times \frac{1}{2} = \frac{1}{8} \\ = > \frac{2x - 1}{4} = \frac{1}{8} \\ = > 2x - 1 = \frac{1}{8} \times 4 \\ = > 2x - 1 = \frac{1}{2} \\ = > 2x = \frac{1}{2} + 1 \\ = > 2x = \frac{1 + 2}{2} \\ = > 2x = \frac{3}{2} \\ = > x = \frac{3}{2} \div 2 \\ = > x = \frac{3}{2} \times \frac{1}{2} \\ = > x = \frac{3}{4}$
