(1 point) Responses (22+40)×(22+7) 22 + 40 × 22 + 7 22×(40×7) 22 × 40 × 7 (22×40)+(22×7) 22 × 40 + 22 × 7 22+(40×7) 22 + 40 × 7 Question 2 Part 2 Which choice shows how to correctly round to check if your answer is reasonable? (1 point) Responses 20×40 20 × 40 20×50 20 × 50 30×40 30 × 40 22×50
The correct way to use the breaking apart method to find the total number of books is:
(22 × 40) + (22 × 7)
To check if this answer is reasonable, you can round the numbers:
20 × 40
So the correct choice for the second question is:
20 × 40
