HESI A2 Math Practice Test 2024

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 calculate the percentage of patients satisfied, divide the number of satisfied patients (120) by the total number of patients surveyed (150) and multiply by 100. So, (120/150) x 100 = 80%. Therefore, the correct answer is A (80%). Choice B (75%) is too low, Choice C (85%) is too high, and Choice D (90%) is also too high based on the given data. Thus, the correct percentage of patients satisfied is 80%.

Correct Answer: D

Rationale: To find 25% of 400, you multiply 400 by 0.25 (25% as a decimal). So, 400 * 0.25 = 100. Therefore, the correct answer is D. Choice A (800) is incorrect as it is 200% of 400. Choice B (10,000) is incorrect as it is 2500% of 400. Choice C (200) is incorrect as it is 50% of 400.

Correct Answer: D

Rationale: To solve the proportion 1.2:x=14:42, we first find the ratio of the first pair (1.2:14) by dividing 1.2 by 14 to get 0.0857. Then, we find the ratio of the second pair (x:42) by dividing x by 42, which equals 0.0857. Therefore, x = 42 * 0.0857 = 3. Hence, the correct answer is D. Choice A is incorrect as 1.2 is not equal to 2. Choice B is incorrect as the ratio cannot be 0. Choice C is incorrect as the ratio is not 1.

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.
