Question

i take a no and divide it by half. by what no should i divide it again to get back the original no?

Answer 1

you should divide 1/2 again to get back the original number...

hope it's right

if yes plz mark as brainliest

let take the number be 10
then its half is 5

the question is what number should be divided again to get back the original number...

let that number be x
then, 5/x = 10
=>10x = 5
=> x= 5/10
= 1/2

hence answer is 1/2

you can also take other numbers instead of 10

like 20,40,60,80,4,8 etc

Answer 2

Let the number taken be x,

According to the question, it is divided by half


$\frac{x}{ \frac{1}{2} } = x \times 2 = 2x$


Then, to get it, let it should be divided by y,


$\frac{2x}{y} = x \\ \\ \frac{2x}{x} =y \\ \\ 2 = y$



Then, it should be divided by 2 to get that number again.




I hope this will help you
