Answer:
5/18
Explanation:
Following order of operations rules, we must do the work inside the parentheses first, and inside the parentheses we must divide as indicated before doing the subtraction.
(2/3)( [3/4] - [1/3] )
3/4 and 1/3 have different denominators so must be rewritten using the LCD (12):
(2/3)(9/12 - 4/12) = (2/3)(5/12) = 10/36 = 5/18
