Bunuel , I approximated the denominator as 2 and chose D as answer.It did strike that it would be a little lower than 2 as the denominator is a little over 2 but generally we approximate like i did earlier.So did we go into so much detail because the answer choices were in detail too?

Yes, the options are very close to each other so you should approximate with more precision.

Hi,

I don't understand the explanation. Why and how we are transforming the equation like that?

Isn't it faster to do it like me:

I just multiplied the equation by 1000, so then there is 4000/2001= and it is very easy to solve.

Thank you

Hi Max,

To make this calculation easier let's round down 2.001 to 2.

Then it will be 4/2 = 2

But, we know that the larger the denominator, the smaller is the number.

Comparing: 4/2.001 is a little bit smaller than 4/2.

This way, the answer choice has to be a little bit smaller than 2.

The answer is 1.999 ( C ).

I hope it helps!

Thanks, Ale
