Final answer:
The sum of 675, 100, and 50, respecting the associative property of addition, is 825.
Step-by-step explanation:
To express the sum 675 + 100 + 50 using properties of arithmetic, we add the numbers together respecting the associative property, which states that the sum remains the same regardless of how the numbers are grouped. In this instance:
675 + (100 + 50) = 675 + 150 = 825
Therefore, the sum of 675, 100, and 50 is 825.
