Because of the commutative property of multiplication, it is true that 3/4 x 4 = 4 x 3/4

. However, these expressions can be calculated in different ways even though the solutions will be the same. Below, show two different ways of solving this problem.

First, show how 3/4 x 4 can be solved using repeated addition. Then, show how 4 x 3/4 can be solved using multiplication and division.
