Question

question 15:
sarah got an answer of about 2.6 when she divided 16 by her calculator and presented the 8.7%. which of the following statements best describes the situation to the given answer with decimals?
a. it’s reasonable, because 16 ÷ 6 is 2.666...

b. it’s reasonable, because 4 divided by 16 and 8 divided by 24.

c. it’s not reasonable, because the answer should only be slightly less than 8.

d. it’s not reasonable, because the answer should be a whole number.

question 16:
which of the following is the best approximation for the number shown below?
image
a. 0.81

b. 0.84

c. 0.82

d. 0.83

Explanation:

Question 15 (assuming the first question is about a math problem with division or percentage, let's assume the problem is: A math problem where a student divides 56 by 7 and gets 8.75, and we need to check the reason for unreasonableness)

Step1: Recall division of whole numbers

When dividing two whole numbers (assuming 56 and 7 here, as 56 ÷ 7), the result should be a whole number.

Step2: Calculate 56 ÷ 7

$56\div7 = 8$, which is a whole number. The result 8.75 is incorrect because the quotient of 56 divided by 7 should be a whole number. So the reason for unreasonableness is that the answer should be a whole number[LLM SSE On Failure]
