Guys, not sure if this has been said before, but I noticed this mistake (at least it appears to me as a mistake) in the OE:

The fifth fraction has the biggest numerator, not the third. I hope this helps. Awesome job, by the way, guys!

Ans is E

I took a simple example
1/2 = 0.5
now add 2 to both numerator and denominator
3/4 = 0.75
now again add 2 to both numerator and denominator
5/6 = 0.83

so as the N and D increases the value also increases. So based on this hypothesis, E is the correct choice.

I can easily notice the gap between the numerators and denominators of the mentioned fractions are the same. So that I just pick the highest numerator and denominator to get the highest number, which is the answer D.
