Of the following fractions, which is less than 3 /5
A) 4/5
B) 6/5
C) 31/15
D) 6/11
E) None of these


Choices A & B have the same denominators as 3%2F5, but are clearly larger than 3%2F5 based on their numerators being > 3

Choice C is greater than 1, since it's an IMPROPER FRACTION. 

Choice D: 6%2F11 and 3%2F5 have an LCD: 55

With denominator 55, 6%2F11, and 3%2F5 become: 30%2F55 and 33%2F55, respectively. This clearly shows that highlight_green%286%2F11%29 is less than 3%2F5
