HESI A2 Math Practice Test 2024

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: D

Rationale: To produce 6 eggs, 2 chickens are required. Therefore, to produce 24 eggs, we need to scale up the number of chickens proportionally. We can set up a ratio: 2 chickens produce 6 eggs, so 1 chicken produces 3 eggs. To produce 24 eggs, we need 8 chickens (24 eggs / 3 eggs per chicken). Therefore, the correct answer is D. Choice A (12 chickens) is incorrect because it does not account for the proportional relationship between the number of chickens and the number of eggs produced. Choice B (4 chickens) is incorrect because it does not consider the required number of chickens to produce the specified number of eggs. Choice C (3 chickens) is incorrect because it does not align with the proportional relationship established in the question.

Correct Answer: A

Rationale: To solve 5 1/3 + 3 1/2, first convert mixed numbers to improper fractions: 5 1/3 = 16/3 and 3 1/2 = 7/2. Then, add the fractions: 16/3 + 7/2 = (32+21)/6 = 53/6. Convert the result back to a mixed number: 53/6 = 8 5/6, which is choice A. Choices B, C, and D are incorrect as they do not represent the correct sum of the given mixed numbers.

Correct Answer: A

Rationale: To convert kilograms to grams, you need to multiply by 1000 as there are 1000 grams in 1 kilogram. Therefore, to find the number of grams in 4 kilograms, you would multiply 4 by 1000, which equals 4000 grams. So, the correct answer is A: 4000. Choice B (40) would be the result if you mistakenly multiplied by 10 instead of 1000. Choice C (500) is the result if you mistakenly added or subtracted a zero. Choice D (0) is clearly incorrect as there are grams in 4 kilograms.

Correct Answer: A

Rationale: To calculate the total number of people working that day, we need to find 68% of the total staff. First, calculate 68% of each category: - Registered nurses: 25 * 0.68 = 17 - Unlicensed assistants: 75 * 0.68 = 51 - Phlebotomists: 5 * 0.68 = 3 - Receptionists and office staff: 6 * 0.68 = 4 - Physicians: 45 * 0.68 = 31 Add these numbers together: 17 + 51 + 3 + 4 + 31 = 106 people (Option A). This is the correct answer as it represents 68% of the total staff. Other options are incorrect as they do not accurately represent 68% of the total staff.
