Evaluate:
((-9+18)/((-3)(-6)))/((32-4(12))/(3(2)))
Let's do the numerator first:
(-9+18)/((-3)(-6)) = 9/18 = 1/2
Now the denominator:
(32-4(12))/(3(2)) = (32-48)/6=-16/6 = -8/3
So now we have:
(1/2)/(-8/3) and you'll recall that to divide fractions, you invert the denominator and multiply, so we get:
(1/2)*(-3/8) = -3/16
