By using the commutative property, the given expression should be simplified as follows: B.
4/3 + 2/3 + 3/4 = 2 + 3/4 = 2 3/4.
By applying the Commutative Property we have:
4/3 + 3/4 + 2/3
Re-arranging the expression, we have;
4/3 + 2/3 + 3/4 = (4 + 2)/3 + 3/4
4/3 + 2/3 + 3/4 = 2 + 3/4
4/3 + 2/3 + 3/4 = 2 3/4
