The value of (10^9-10^2)/(10^7-10^3) is closest to which of the following?
Pick:	A) 1	B) 10	C) 10^2	D) 10^3	E) 10^4
Because the question asks for what value isclosestthe question invites approximation.   Let's look at the numerator:   10^9 - 10^2   10^9 is HUGE compared to 10^2.   So 10^9 - 10^2 is very close to 10^9 itself. (Just as 100 - 0.0001 is very close to 100 itself).   Likewise, 10^7 is HUGE compared to 10^3.   So 10^7 - 10^3 is very close to 10^7.   So we have:   10^9/10^7   or 10^(9-7) = 10^2.   10^2hoose 10^2.
