HESI A2 Math Practice Test 2024

Correct Answer: A

Rationale: To convert fluid ounces to gallons, we know that 1 gallon is equal to 128 fluid ounces. Therefore, to find out how many gallons are in 3 fluid ounces, we divide 3 by 128 which equals 0.0234 gallons (A). Choice B (0.5 gallons) is way too high for 3 fluid ounces as it is closer to 64 fluid ounces. Choice C (0.38 gallons) and Choice D (0.12 gallons) are also incorrect as they do not align with the conversion factor of 1 gallon = 128 fluid ounces.

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 find the number of days it will take the man to read 798 pages, first calculate the total number of chapters: 798 pages / (6 pages/chapter) = 133 chapters. Since he reads 2 chapters a day, divide the total chapters by 2 to get 133 chapters / 2 chapters/day = 66.5 days. Therefore, the correct answer is A: 66 & 1/2. Incorrect Choices: B: 399 - Incorrect as it does not reflect the correct calculation. C: 75 & 1/2 - Incorrect, the calculation is incorrect. D: 133 - Incorrect, this represents the total number of chapters, not the number of days.

Correct Answer: C

Rationale: To convert scientific notation (4.82 x 10^3) to standard form, we multiply the coefficient (4.82) by 10 raised to the exponent (3). This gives us 4.82 x 1000 = 4820. Therefore, the value of the number in standard form is 4820. Explanation of incorrect choices: A: 0.00482 - This choice is incorrect because it represents a smaller value than the original number. B: 0.482 - This choice is incorrect as it is also smaller than the original number. D: 4820000 - This choice is incorrect as it represents a larger value than the original number.

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.
