Question

if you subtarct 1/2 from a number and multiply the result by 1/2 you get 1/8. What is the number? I need the answer with explaining please....

Answer 1

Step-by-step explanation:

So let the number be t.

Now, we're given that 1/2 is subtracted from the number.

The equation becomes

$t - \frac{1}{2} = \frac{2t - 1}{2}$

Now, that is multiplied by 1/2.

$\frac{2t - 1}{2} \times \frac{1}{2} = \frac{2t - 1}{4}$

And the result of the equation is 1/8 which goes something like this

$\frac{2t - 1}{4} = \frac{1}{8} \\ \\ 16t - 8 = 4 \\ \\ 16t = 12 \\ \\ t = \frac{3}{4}$

(Cross multiplication is done above.)

Therefore, the number is 3/4.

I hope this is enough for the question.
