HESI A2 Math Practice Test 2024 Questions

Question 1 of 5

What is the result of adding 7/21 + 10/21?

Correct Answer: A

Rationale: To add fractions, ensure the denominators are the same. Here, both fractions already have a common denominator of 21. Add the numerators: 7 + 10 = 17. So, the result is 17/21 (choice A). Other choices are incorrect because: B: 15/21 - Incorrect, the sum of the numerators is 17, not 15. C: 9/21 - Incorrect, the sum of the numerators is 17, not 9. D: 10/21 - Incorrect, this is just one of the fractions being added, not the result of the addition.

Question 2 of 5

12 is a/an:

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.

Question 3 of 5

In the number 743.25, which digit represents the tenths place?

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.

Question 4 of 5

A person consumed 75 grams of protein. This is 30% of the recommended daily intake (RDI) for protein. How many grams of protein does the person need to consume to meet the full RDI?

Correct Answer: A

Rationale: The correct answer is A (250 grams). To calculate the full RDI, we use the formula: RDI = Consumed Amount / Percentage Consumed. Given, Consumed Amount = 75 grams and Percentage Consumed = 30%. Therefore, RDI = 75 / 0.30 = 250 grams. The other choices are incorrect because they do not match the calculated value based on the given information. Choice B, C, and D are all higher than the correct calculation of 250 grams, so they do not align with the required amount based on the 30% consumption.

Question 5 of 5

Convert the following military time to regular time: 15:17:52.

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.
