Since I'm in a good mood, I'll share one of my favourite quant tricks with you. BOW TIE. You may have already known this but it's the easiest way to figure out which fraction is bigger.

7 OR 6
12 11

Multiply 12 by 6 = 72. That's the value of the fraction on the right.

Multiply 11 by 7 =77. That's the value of the fraction on the left.

Left value is bigger, hence, 7/12 is more than 6/11. I actually got a question on data sufficiency and had I not known this, I would have got it wrong.


That's a great trick!! I certainly had never seen that before, or if I had I'd forgotten it. The only thing that might cause confusion is attributing the value to the right fraction. I could see myself messing that up if flustered. But I guess you just remember that each bow tie value relates to the numerator, correct?

Great trick though. Are there many more tricks like that in the forum IVY?
