( ) # Benchmark Question Misconceptions 1 AR.2.2 Which of the following describes the equation If students chose A, B or C, they did 24 ÷ 3 = 56 ÷ 8? not divide either quotient correctly. A. The equation is true because the expressions on each side have a quotient of 8 B. This equation is true because the expressions on each side have a quotient of 7. C. This equation is false because the expressions on each side have a quotient of 8. D. This equation is false because the quotient on the left is 8 and the quotient on the right is 7. 2.
