p/3-3p/8=3

p-3p/8=9

p-3p=72

-316

I am not sure if I did this right. Just guessing.

You should have made the denominators alike so that you could subtract the fractions easier.

p/3-3p/8=3
8p/24 - 9p/24 = 3
-p/24 = 3
-p= 3(24)
-p= 72
-p/-1 = 72/-1
p=-72

Easier way ...

multiply each term by the LCD, which is 24, so

8p - 9p = 72
-p = 72
p = -72

is this correct? simplify: ((1+(2)/(3))/((2+(1)/(2)) My answer: (2)/(3) assuming that 2/3 and 1/2 are separate fractions, 8/3 x 5/2 40/6 20/3 hmm.. perhaps you need to check your arithmetic. unless i'm wrong, which wouldn't be surprising
