HESI A2 Math Practice Test 2024

Correct Answer: A

Rationale: The nurse's schedule rotates every 4 days, working 3 days and having 1 day off. If the first day off is Monday, the next day off will be on the 4th day, which is Friday. The pattern is: Work - Work - Work - Off. Therefore, the correct answer is A: Friday. Other choices are incorrect because the pattern of the nurse's schedule clearly indicates that the second day off falls on the 4th day, which is Friday in this case.

Correct Answer: C

Rationale: The correct answer is C: 9:00 PM. To convert 2100 to standard time, subtract 12 hours from 2100 since military time is based on a 24-hour clock. 2100 - 1200 = 900, which translates to 9:00 PM. Choice A (12:00 PM) is incorrect as it would be noon, not evening. Choice B (2:00 AM) is incorrect as it represents the early morning. Choice D (2:00 PM) is incorrect as it is in the afternoon, not evening.

Correct Answer: A

Rationale: To solve 7 1/8 + 2 4/12, first convert 2 4/12 to an improper fraction: 2 4/12 = 2 + 1/3 = 2 1/3 = 7/3. Now, add 7 1/8 and 7/3 by finding a common denominator, which is 24. 7 1/8 = 57/8. Add 57/8 and 7/3 to get 183/24. Simplify 183/24 to 9 11/24, which is the correct answer (A). Choices B, C, D are incorrect as they do not match the calculated result.

Correct Answer: A

Rationale: To find the total cups of sugar needed for 2.5 batches, we multiply the cups of sugar per batch (1.75) by the number of batches (2.5). 1.75 cups x 2.5 batches = 4.375 cups. Since we can't have a fraction of a cup in reality, we round up to the nearest whole number, which is 4 cups. Therefore, the correct answer is A: 4 cups. Choice B (3 cups) is incorrect as it does not account for the additional half batch. Choice C (5 cups) is incorrect as it overestimates the amount of sugar needed. Choice D (3 cups) is also incorrect as it does not consider the extra half batch.

Correct Answer: D

Rationale: To find the percentage equivalent of a decimal number, you multiply the decimal by 100. So, for 0.45, you get 0.45 x 100 = 45%. Therefore, the correct answer is D. Choice A (4.5%) is 10 times greater than 0.45, Choice B (0.045%) is 100 times smaller, and Choice C (0.45%) is the same as the decimal, not the percentage equivalent.
