HESI A2 Math Practice Test 2023 Questions
Question 1 of 5
How many milliliters are in 5 pints of water?
Correct Answer: A
Rationale: To convert pints to milliliters, we need to know that 1 pint = 473.176 milliliters. Therefore, 5 pints would be 5 x 473.176 = 2365.88 milliliters. Rounding up, we get approximately 2400 milliliters. This is why choice A (2400 milliliters) is correct. Choices B, C, and D are incorrect because they do not accurately convert pints to milliliters based on the conversion factor provided.
Question 2 of 5
How many liters are in 2,000 milliliters?
Correct Answer: C
Rationale: To convert milliliters to liters, you need to divide by 1,000 since there are 1,000 milliliters in 1 liter. So, 2,000 milliliters divided by 1,000 equals 2 liters. Therefore, the correct answer is C: 2 liters. Choice A is incorrect as it incorrectly doubles the conversion factor. Choice B is incorrect as it doesn't account for the conversion from milliliters to liters. Choice D is incorrect as it duplicates choice A.
Question 3 of 5
What is 80% of 55?
Correct Answer: B
Rationale: To find 80% of 55, you multiply 55 by 0.8 (which is the decimal equivalent of 80%). So, 55 * 0.8 = 44. Therefore, the correct answer is B (44). Choice A (40) is incorrect as it represents 80% of 50, not 55. Choices C (39) and D (45) are also incorrect calculations.
Question 4 of 5
Subtract 12 1/8 - 9 1/2.
Correct Answer: A
Rationale: To subtract mixed numbers, first convert them to improper fractions. 12 1/8 = 97/8 and 9 1/2 = 19/2. Then, subtract the fractions: 97/8 - 19/2 = 97/8 - 38/8 = 59/8. Finally, convert the result back to a mixed number: 59/8 = 7 3/8. Therefore, the correct answer is A: 2 5/8. Choices B, C, and D are incorrect because they do not match the result of the subtraction calculation.
Question 5 of 5
Subtract 32 divided by 8\9.
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.
