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
Max
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
