Answer:
(4b - 6a + 9) / 6ab.
Step-by-step explanation:
The lowest common denominator of 3a, b and 2ab = 6ab
Now to get the numerator we divide each of the 3 denominators into 6ab and multiply the result by the corresponding numerator:
So we have:
2/3a - 1/b + 3/2ab
= (2*2b - 6a +3*3) / 6ab
= (4b - 6a + 9) / 6ab.
