What is the answer to number 2 and how did you solve it ?

It would be G, because the points are all less than or equal to 0.85, and greater than or equal to 0.15. 

Ok so on the line, the very left is 0 and the very right is one.  The lines in between are increasing by .1 as they go. The question is asking to compare point K and Z. Point K represents about .15 and Z represents .85          SO .85>.15, or H is your answer

Hope that helped! If you still dont get it ask and i can try to re explain :)

The answer for you question is b
