HESI A2 Practice Test Math Questions
Question 1 of 5
What is the result of adding 5 2/9 and 1 2/9?
Correct Answer: A
Rationale:
To add mixed numbers with fractions, first add the whole numbers together: 5 + 1 = 6.
Then add the fractions: 2/9 + 2/9 = 4/9. Combining the whole number and the fraction parts gives 6 4/9.
Therefore, the correct answer is 6 4/9.
Choice B (7 5/9) is incorrect as the fractions were not added correctly.
Choice C (7) is incorrect as it does not account for the fractions.
Choice D (5 2/9) is one of the original numbers and not the sum of both.
Question 2 of 5
How many ounces are in 8 & 1/4 pints?
Correct Answer: C
Rationale:
To convert 8 1/4 pints to ounces, first convert the mixed number to an improper fraction: 8 1/4 = 33/4. There are 16 ounces in 1 pint. Now, multiply 33/4 by 16 ounces per pint: 33/4 x 16 = 132 ounces.
Therefore, the correct answer is 132 oz.
Choice A (136 oz) is incorrect because it does not result from the correct conversion.
Choice B (128 oz) is incorrect as it is a miscalculation.
Choice D (130 oz) is incorrect as well, not derived from the accurate conversion process.
Question 3 of 5
The height of a building is 150 feet. If each floor of the building is 12 feet high, how many floors are in the building?
Correct Answer: A
Rationale:
To determine the number of floors in the building, divide the total height of the building (150 feet) by the height of each floor (12 feet). 150 feet · 12 feet per floor = 12.5 floors. Since floors cannot be in fractions, the answer is rounded down to the nearest whole number, which is 13 floors.
Therefore, the correct answer is A: 13 floors.
Choice B (15 floors) is incorrect because the calculation results in 12.5 floors, which should be rounded down.
Choices C (10 floors) and D (18 floors) are incorrect as they do not accurately reflect the division result and rounding down process.
Question 4 of 5
A roast was cooked at 325°F in the oven for 4 hours. The internal temperature rose from 32°F to 145°F. What was the average rise in temperature per hour?
Correct Answer: C
Rationale: The temperature increased from 32°F to 145°F, resulting in a total increase of 145°F - 32°F = 113°F. Dividing this total increase by the 4 hours of cooking time gives an average rise of 113°F · 4 = 28.25°F per hour, which can be rounded to 28°F per hour.
Therefore, the correct answer is 28.
Choice A (20) is incorrect because it does not reflect the actual average rise in temperature per hour.
Choice B (32) is incorrect as it does not consider the total temperature increase and divide it by the total hours.
Choice D (37°F/hr) is incorrect as it does not match the calculated average rise in temperature per hour.
Question 5 of 5
An office manager makes photocopies for the entire staff each day. At the end of the week, she finds that the photocopy machine has made a total of 3,475 copies. If 6 people used the copier and each person made the same number of copies, how many copies did each person make?
Correct Answer: A
Rationale:
To find out how many copies each person made, divide the total number of copies made (3,475) by the number of people who used the copier (6). This gives 579 copies per person (3,475 · 6 = 579).
Therefore, each person made 579 copies.
Choices B, C, and D are incorrect as they do not result from the correct division of the total number of copies by the number of people who used the copier.
