Remember, like all GMAT Quantitative problems, this is a no calculator problem. I. \(\frac{47}{150}\)
II. \(\frac{111}{330}\)
III. \(\frac{299}{900}\)
Rank those three in order from smallest to biggest. (A) I, II, III (B) I, III, II (C) II, I, III (D) II, III, I (E) III, I, IIFor a full discussion of this question and the topic of number sense, see this blog: http://magoosh.com/gmat/2012/numbersenseforthegmat/Experts, feel free to share you thoughts on what number sense is and how to develop it.

I said "smallest to largest", but then when I did it in my head, I put them in order from largest to smallest! Sorry about any confusion. Mike

I. 47/150 is almost 50/150 = 1/3. It is (5047)/150 = 3/150 = 1/50 away from 1/3 II. 111/330 is beyond 110/330 = 1/3 III. 299/900 is almost 300/900 = 1/3. 299/900 is (300299)/900 = 1/900 away from 1/3 I is the farther to the left of 1/3 than III while II is the largest. Rank: I,III,II

Try and get all the denominators the same, i.e. in terms of 900:
I: 47x6/150x6 = 282/900
II: 111x3/330x3 =:(approx) 333/990
III: 299/900
From the above, we know that I is the smallest (as it has the smallest numerator) and hence comes first, eliminate options C,D and E. Only left with A & B.
299/900 will definitely be greater than 333/990 as if we find the accurate multiple by which to get 900 in II, it will give us a numerator being less than 299. Hence III<I
Final order: I,III,II
Option B

Rank those three in order from smallest to biggest. (A) I, II, III (B) I, III, II (C) II, I, III (D) II, III, I (E) III, I, IIFor a full discussion of this question and the topic of number sense, see this blog: http://magoosh.com/gmat/2012/numbersenseforthegmat/Experts, feel free to share you thoughts on what number sense is and how to develop it. I. 47/150 = 282/900 II. 333/990 >330/990=1/3= 300/900 III. 299/900 So, II >III>I or as per mikemcgarry I< III < II Answer B

It can also be solved by reducing the values. So, I. 47/150 << 50/150 =1/3 II. 111/330 > 110/330 = 1/3 III. 299/900 just< 300/900 = 1/3 So, II >III>I or as per mikemcgarry I< III < II Answer B
