HESI A2 Practice Test Math Questions
Question 1 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.
Question 2 of 5
There are 225 pieces of candy in a large jar. Ben wants to give the 25 campers in his group an equal amount of candy. How many pieces of candy will each camper receive?
Correct Answer: A
Rationale:
To determine how many pieces of candy each camper will receive, divide the total number of pieces of candy (225) by the number of campers (25): 225 · 25 = 9 pieces per camper.
Therefore, each camper will receive 9 pieces of candy to ensure they all get an equal amount.
Choice B, 7 pieces, is incorrect because the total number of candy pieces divided equally among 25 campers results in 9 pieces per camper, not 7.
Choice C, 8 pieces, and choice D, 6 pieces, are also incorrect as they do not accurately reflect the division of 225 pieces of candy among 25 campers.
Question 3 of 5
A woman received a bottle of perfume as a present. The bottle contains 1/2 oz of perfume. How many milliliters is this?
Correct Answer: A
Rationale: 1/2 oz of perfume is equal to approximately 15 mL.
To convert ounces to milliliters, we need to know that 1 oz is approximately 30 mL.
Therefore, half an ounce, which is 1/2 oz, would be half of 30 mL, which equals 15 mL.
Choice B, 20 mL, is incorrect as it does not correspond to the conversion factor of 1 oz to 30 mL.
Choice C, 10 mL, is incorrect as it is half of the actual value.
Choice D, 50 mL, is incorrect as it is the value of 1 oz rather than half an ounce.
Question 4 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 5 of 5
What is 20% of 150?
Correct Answer: B
Rationale:
To find 20% of 150, you need to multiply 150 by 0.20: 150 0.20 = 30.
Therefore, 20% of 150 is indeed 30.
Choice A (25) is incorrect as it represents 20% of 125, not 150.
Choice C (35) is incorrect as it represents more than 20% of 150.
Choice D (20) is incorrect as it is the original percentage to find.
