HESI A2 Math Practice Test 2024

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: 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: C

Rationale: To multiply 4/9 by 1 & 4/5 by 2/5, we first multiply the fractions separately. 4/9 x 1 = 4/9, 4/5 x 2/5 = 8/25. Then we multiply the results: 4/9 x 8/25 = (4 x 8) / (9 x 25) = 32 / 225 = 8/25. Therefore, the correct answer is C. Choices A, B, and D are incorrect because they do not result from the correct multiplication of the given fractions.

Correct Answer: C

Rationale: To subtract 12 - 7 & 4\5, first convert 12 to a mixed number: 12 = 11 & 5\5. Then, subtract the whole numbers: 11 - 7 = 4. Next, subtract the fractions: 5\5 - 4\5 = 1\5. Therefore, the correct answer is 4 & 1\5 (Choice C). Choices A, B, and D are incorrect as they do not accurately represent the result of the subtraction calculation.

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.
