I was able to solve: x divided by 3/4 = 6 by multiplying 6 x 3/4 = 4 1/2. Just not sure how to solve the first problem. If I change 5 2/5 into mixed number,I still don't know what to do next.

3 divided by x/9 = 27/5 ?

**Steve**, Sunday, December 9, 2012 at 8:05pm3/(x/9) = 3*(9/x) = 27/x

so, now you have

27/x = 27/5

x = 5

.

Steve, thanks for the answer. But, I'm still not sure how you solved for x after getting 27/x= 27/5. Did you multiply both sides by 1/27 to get x by itself?
