HESI A2 Math Practice Test 2023

Correct Answer: C

Rationale: To convert gallons to ounces, we know that 1 gallon equals 128 ounces. Therefore, to find out how many ounces are in 2.5 gallons, we multiply 2.5 by 128. 2.5 * 128 = 320 ounces. Therefore, the correct answer is C: 320 ounces. Other choices are incorrect because they do not correctly calculate the conversion from gallons to ounces. A, B, and D do not consider the correct conversion factor of 128 ounces per gallon.

Correct Answer: B

Rationale: To calculate speed, use the formula: speed = distance/time. In this case, the car traveled 240 miles in 4 hours. Therefore, speed = 240 miles / 4 hours = 60 mph. Choice B is correct as it represents the calculated speed accurately. Choice A (50 mph) is too low, Choice C (55 mph) is close but not accurate, and Choice D (75 mph) is too high based on the calculation.

Correct Answer: A

Rationale: To convert millimeters to meters, we divide by 1000 since there are 1000 millimeters in a meter. Therefore, 3000 millimeters divided by 1000 equals 3 meters. Choice A is correct. Choices B, C, and D are incorrect because they do not correctly convert millimeters to meters. Choice B is 30 times the correct answer, choice C is 10 times less, and choice D is 100 times more.

Correct Answer: D

Rationale: To find the total number of pages the man reads per day, we multiply 2 chapters/day by 6 pages/chapter, which equals 12 pages/day. To determine how many days it will take to finish a 798-page book at 12 pages/day, we divide 798 by 12, resulting in approximately 66.5 days. This is why choice D is correct. Choice A (133 days) is incorrect because it overestimates the time needed, while choice B (399 days) and choice C (75 days) underestimate the time required to finish the book.

Correct Answer: A

Rationale: To subtract 32 divided by 8\9, first divide 32 by 8 to get 4. Then divide 4 by 9, which equals 4\9. Subtracting 4\9 from 32 gives 36, which is the correct answer (A). Choice B (32) is incorrect as it only divides 32 by 8, not considering the second division by 9. Choices C (40) and D (44) are incorrect as they do not follow the correct division and subtraction steps.
