Question
Which answer choice is equal to the expression below? 7×8×97×8×9Select one:9 × 8 × 7highlight_off7 + 8 + 9highlight_off7 ÷ 8 ÷ 9highlight_off9 + 8 + 7highlight_off
Solution
The correct answer is 9 × 8 × 7. Here's why:
The original expression is 7×8×97×8×9.
This can be rearranged (due to the commutative property of multiplication) as 9×8×7×9×8×7.
However, the second half of the expression (×9×8×7) is not included in the answer choices.
So, the answer choice that matches the first half of the rearranged expression (9×8×7) is the correct one.
