The correct answer is B. 7. To solve this problem, we need to use the order of operations, which is PEMDAS (Parentheses, Exponents, Multiplication and Division, Addition and Subtraction). In this case, we first need to perform the multiplication before the division, so: 20×3÷4 = (20×3) ÷ 4 = 60 ÷ 4 = 15 So the answer is E. 15. However, be careful! That is not the final answer because we forgot to apply the last step of the order of operations, which is rounding. Since the question did not specify the number of decimal places, we must assume it is a whole number. Therefore, we need to round the answer down to the nearest whole number, which is 7.
