HESI A2 Math Practice Test 2024

Correct Answer: A

Rationale: To determine who ate more, we compare 3/5 of Sally's lunch to 75% of John's. Converting 75% to a fraction gives us 3/4. Thus, 3/5 is less than 3/4. Therefore, John ate more than Sally. Option A is correct. Option B is incorrect as Sally ate less. Option C is incorrect as their consumption is not equal. Option D is incorrect as both of them ate some portion of their lunch.

Correct Answer: A

Rationale: Step-by-step rationale: 1. An even number is divisible by 2. 2. 12 is divisible by 2 (12 ÷ 2 = 6). 3. Therefore, 12 is an even number (Choice A). Summary: B: Incorrect - Odd numbers are not divisible by 2. C: Incorrect - Prime numbers have only 2 factors. D: Incorrect - Composite numbers have more than two factors.

Correct Answer: B

Rationale: The military time 15:17:52 is equivalent to 3:17:52 PM in regular time. To convert from military time to regular time, we subtract 12 from the hour if it is greater than 12 to get the PM time. Therefore, 15 - 12 = 3, indicating it's in the afternoon. The correct answer is B (3:17 PM). Choice A (2:17 PM) is incorrect because 15 is greater than 12, so it would be in the afternoon. Choice C (5:17 AM) is incorrect because 15 is in the afternoon, not morning. Choice D (9:17 AM) is incorrect because 15 is in the afternoon, not morning.

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.

Correct Answer: A

Rationale: To convert a decimal to a percent, you multiply by 100. In this case, 0.09 * 100 = 9%. Therefore, the correct answer is A: 9%. Choice B (90%) is incorrect as it would be the result of multiplying by 1000, not 100. Choice C (1%) is incorrect as it would be the result of moving the decimal point two places to the right without multiplying by 100. Choice D (0%) is incorrect as the number is not zero, it's 0.09.
