If 2(x-3)=2(x/2-1/3), x=?
I have the kaplan online course, and through most explanations of fraction problems, I am finding that they don't use mixed terms in their work.. .i.e. 7x=16/3 as opposed to 7x=5 1/3..
Should I always use non-mixed terms when working with fractions? Any other simple tips that will help?
Thanks!

If you need to do any arithmetic (especially any division or multiplication), you'd always want to use the expression '16/3', and not '5 1/3', unless you're only concerned with getting an estimate. I can't see how you'd easily go about dividing, say, 5 1/3 by 7 1/5, but if you write those fractions as 16/3 and 36/5 it's straightforward enough:
(16/3)/(36/5) = (16/3)*(5/36) = 20/27
You infrequently see mixed fractions on the GMAT, typically only in word problems.
