Question

Select the multiplication sentence that applies the associative property of multiplication to the example. Example: 1 × (9 × 5) = 45 A. 1 × (9 + 5) = 14 B. (8 × 5) + 5 = 45 C. (1 + 9) × 5 = 50 D. (1 × 9) × 5 = 45

Answer 1

The example is 1 x (9 x 5) = 45

Using the associative property of multiplication, we basically rearrange the parenthesis to group the first two terms like so: (1 x 9) x 5

So this is why choice D (1 x 9) x 5 = 45 is the answer

This means that 1 x (9x 5) = (1 x 9) x 5 is a true equation
