HESI A2 Math Practice Test 2024

Correct Answer: D

Rationale: To calculate the total days off, add Bill's remaining vacation days (2.5) and sick days (1.25): 2.5 + 1.25 = 3.75 days. Since Bill is using all his sick days and vacation days, he will have 3 full days off work. Therefore, the correct answer is D (4 days). Choices A, B, and C are incorrect as they do not consider the combination of remaining days and assume a different outcome.

Correct Answer: A

Rationale: To convert centimeters to inches, we use the conversion factor 1 inch = 2.54 centimeters. Therefore, to convert 65.4 centimeters to inches, we divide 65.4 by 2.54. The calculation is 65.4 / 2.54 = 25.74 inches. This is why choice A (25.74) is correct. Choices B, C, and D are incorrect as they do not correctly convert centimeters to inches.

Correct Answer: A

Rationale: To find out how much more water is needed, subtract the amount already added (1/3 cup) from the total needed (4/5 cup): 4/5 - 1/3 = (12/15) - (5/15) = 7/15 cups. Therefore, the correct answer is A (7/15 cups). Other choices are incorrect because they do not result from the correct calculation. B is more than the total needed, C is the amount already added, and D is less than the amount needed.

Correct Answer: A

Rationale: To calculate the total number of patients monitored, we add the number of patients each nurse monitored: 6 + 8 + 12 = 26 patients. Therefore, the correct answer is A (26 patients). Nurse 1 monitored 6 patients, Nurse 2 monitored 8 patients, and Nurse 3 monitored 12 patients, totaling 26 patients. Choices B, C, and D are incorrect because they do not accurately represent the sum of patients monitored by all three nurses.

Correct Answer: C

Rationale: The tenths place is the first digit to the right of the decimal point. In the number 743.25, the digit 2 is in the tenths place because it is the first digit to the right of the decimal point. Therefore, the correct answer is C. Explanation for why the other choices are incorrect: - A: 3 is in the units place, not the tenths place. - B: 4 is in the tenths place, not the tenths place. - D: 5 is in the hundredths place, not the tenths place.
