Question

What should be added to `(-1)/2` to obtain the nearest natural number?

Answer 1

We know that, nearest number of `(-1)/2` is 1.

Let x be added to `-1/2` to obtain 1.

Then, `-1/2 + x = 1`

⇒ `x = 1 + 1/2 = (2 + 1)/2`

⇒ `x = 3/2`

Hence, `3/2` should be added to `(-1)/2` to obtain the nearest natural number.
