This is a fun one. Came from the GRE (yeah i know, this is GMAT but this question showed up with a surprise):
Column a:
4.1 + (1/3)
Column b:
5.1-(2/3)
The quantity in Column A is greater.
The quantity in Column B is greater.
The two quantities are equal.
The relationship cannot be determined from the information given.
[spoiler]The two quantities are equal. HOW?!
4.1+(1/3) =4.1+(1/3)
5.1-(2/3)=(4.1 + 1 )-(2/3)
=4.1 + (1-(2/3))
=4.1+ (1/3)
Mathematically when shot into a calculator:
Column a is 4.43, Column b is 4.44 (is what i had)
F YOU ETS!

I'm sorry, but they're right about this one. You forget that 1/3 = 0.33333.... or 0.(6) and that 2/3 = 0.6666.... or 0.(3). This means that, since you have an infinity of either 3 or 6 after the 0, then your calculator will give you approximate answers.

Easiest way I have of figuring this out is just removing the .1 from both numbers
Column a:
4.1 + (1/3)
Column b:
5.1-(2/3)
BECOMES
Column a:
4+ (1/3) = 4 & 1/3
Column b:
5-(2/3) = 4 & 1/3
Thus they are equal.
