Question

Which expressions are equivalent to the expression 32 ÷ (8 – 4)?

Choose exactly two answers that are correct.

A.
18 – 2 ÷ 2

B.
48 ÷ (10 – 4)

C.
15 – 21 ÷ 3

D.
36 – 15 ÷ 3 + 1

Answer 1

32/4 = 8. Now lets see which expression comes out to 8. 18-4 = 14 so it cannot be a. 48/6 is equal to 8 so one of them is B. 15 - 7 is also 8, so C is the second answer. Just to make sure we evaluate d, which comes out to 30.
