(3/4-(2/3)^2)/(3/2+7/9) =
(3/4 - 4/9) INSIDE simplifes to (1/36)(3•9 - 4•4) which is 11/36
(3/2+7/9) simplifies to (27+14)/18 which is 41/18.
You now have this type of problem: fraction#1 divided by fraction#2.
Equivalent to fraction#1 • reciprocal of fraction#2, i.e. (11/36)(18/41) which is 11/(2•41) = 11/82
