Question

If you subtract 1/2 from a number and multiply the result 1/2 , you got 1/8 . What is the number? please answer step by step. ​

Answer 1

Answer:

$\boxed{the \ number \ is \ \bf{\frac{3}{4}}}$

Step-by-step explanation:

If you subtract 1/2 from a number and multiply the result 1/2 , you got 1/8 .

____________________________

let the number be ''a''

If you subtract 1/2 from a number,the result is

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

multiply the result by 1/2 , you get 1/8 .

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

The number is 3/4

Answer 2

let's x be the number than a per questions

the LCM of denominator is 8

so multiplying by 8 on both side

1/2*8= 4(x-1/2)= 1

4x-2= 1

transposing 2 to RSH

=4X= 1+2

=4X=3

DIVIDING 4 ON BOTH SIDE

4X=3

TRANSPOSING 4 TO RHS

X=3/4

THEREFORE X= 3/4

THIS IS YOU ANSWER
