Question 1 of 5

Which of the following is listed in order from least to greatest? (-3/4, -7 4/5, -8, 18%, 0.25, 2.5)

Correct Answer: D

Rationale: The correct order from least to greatest is -8, -7 4/5, -3/4, 18%, 0.25, 2.5. To determine this: 1. Start with the integers: -8 is the smallest, followed by -7 4/5. 2. Then, consider the fractions: -3/4 is smaller than -7 4/5. 3. Next, compare the decimals: 0.25 is smaller than 18% (which is equivalent to 0.18). 4. Finally, compare 2.5 with the rest; it is the largest. Explanation for incorrect choices: - Choice A: Incorrect order as -8 is greater than -7 4/5. - Choice B: Incorrect order as -3/4 should come before -7 4/5. - Choice C: Incorrect order as 2.5 should be the largest, not the smallest in the list.

Question 2 of 5

Dr. Lee observed that 30% of all his patients developed an infection after taking a certain antibiotic. He further noticed that 5% of that 30% required hospitalization to recover from the infection. What percentage of Dr. Lee's patients were hospitalized after taking the antibiotic?

Correct Answer: A

Rationale: To calculate the percentage of Dr. Lee's patients hospitalized, we need to find 5% of the 30% who developed an infection. 5% of 30% is 1.5%. Therefore, the correct answer is A: 1.50%. Choice B (5%) is incorrect because it represents the percentage of patients who developed an infection, not those hospitalized. Choice C (15%) is incorrect as it is the total percentage of patients who developed an infection, not just those hospitalized. Choice D (30%) is incorrect as it represents the initial percentage of patients who developed an infection, not those hospitalized.

Question 3 of 5

Which of the following is listed in order from least to greatest? (-3/4, -7 4/5, -8, 18%, 0.25, 2.5)

Correct Answer: D

Rationale: The correct order from least to greatest is -8, -7 4/5, -3/4, 18%, 0.25, 2.5. To determine this: 1. Start with the integers: -8 is the smallest, followed by -7 4/5. 2. Then, consider the fractions: -3/4 is smaller than -7 4/5. 3. Next, compare the decimals: 0.25 is smaller than 18% (which is equivalent to 0.18). 4. Finally, compare 2.5 with the rest; it is the largest. Explanation for incorrect choices: - Choice A: Incorrect order as -8 is greater than -7 4/5. - Choice B: Incorrect order as -3/4 should come before -7 4/5. - Choice C: Incorrect order as 2.5 should be the largest, not the smallest in the list.

Question 4 of 5

While at the local ice skating rink, Cora went around the rink 27 times in total. She slipped and fell 20 of the 27 times she skated around the rink. What approximate percentage of the times around the rink did Cora not slip and fall?

Correct Answer: C

Rationale: To find the percentage of times Cora did not slip and fall, subtract the times she fell (20) from the total times around the rink (27): 27 - 20 = 7. Then, divide the times she did not fall (7) by the total times (27): 7 / 27 ≈ 0.259 or 26%. The correct answer is C (26%), as it represents the approximate percentage of times Cora did not slip and fall. Explanation for other choices: A: 37% - Incorrect. This percentage does not accurately represent the times Cora did not slip and fall. B: 74% - Incorrect. This percentage is too high and does not align with the calculation. D: 15% - Incorrect. This percentage is too low and does not align with the calculation.
