Hi all I find I have some difficulty on numbers related LR questions, there was a MBT question on pt 89 dealing with average numbers of students in night classes and an easier question on pt 80.1.2 (flaw question) where it's a numerator denominator trap.

I remember someone saying "you have to know 2 of 3 things to make a valid inference, you have to know at least 2/3 of the numerator, denominator, or the %." Am I remembering this correctly?

Also does anyone have any tips from figuring these numbers questions out easily? Thanks!
