2/3 times 3/4 = 6/12 or 1/2. That's how much they ate.
2/3 - 1/2 is also 4/6 - 3/6 = 1/6. that's how much was left.

You have to first find the common denominator for the 2 separate problems (also, logically, how many possible brownies is "a pan"---I would say no more than 16, but in this case the LCD for the 2 questions is 12)
If 1/3 of the brownies is gone by the time she takes them to school that's 4 of them, leaving 8. If her friends eat 3/4 of those, they eat 6 of the 8, leaving 2 brownies, or 2 of the original 12. 2/12=1/6.
Answers: Her friends ate 3/4 of them, or 6 brownies.
There is 1/6 of the pan left, or 2 brownies.

Her friends ate 1/2 of them (2/3*3/4=6/12=1/2)
There would be 1/6 left.
(Use 90, as a hypothetical number that there was originally, and work forwards)
