How would I solve the second problem with proportions? I tried to do it with proportions but I couldn't get the answer so I just solved it another way.
Ms. Sue
I'd start with the number of hours in 3 days. 24 * 3 = 72

2/6 = x/72

Oh I see how to solve it now. That's what I needed. Thanks! :D
Ms. Sue
You're welcome. :-)
