Math HESI A2 Practice Test Questions

Question 1 of 5

What is 75% of 80?

Correct Answer: D

Rationale: To find 75% of 80, you multiply 80 by 0.75 (which represents 75%). 80 * 0.75 = 60. Therefore, the correct answer is D: 60. Choice A (35) is incorrect because it is not 75% of 80. Choice B (45) is also incorrect as it is not the correct calculation for 75% of 80. Choice C (70) is incorrect as well since it does not represent 75% of 80.

Question 2 of 5

You need to buy cardboard to cover a rectangular box with dimensions 40cm by 30cm by 25cm. Considering only the exterior surfaces (not flaps or openings), how much cardboard do you need (assume one sheet covers 0.5 sq m)?

Correct Answer: C

Rationale: To calculate the surface area of the rectangular box, you need to find the area of each face. The box has 6 faces, and each face's area is 40*30cm=1200cm². Therefore, the total surface area is 6*1200cm²=7200cm²=0.72m². Since one sheet covers 0.5m², you need 0.72m²/0.5m²=1.2 sheets of cardboard, which is equivalent to 1.2m². This is why option C, 1.2 sq m, is the correct answer. Option A (0.3 sq m), B (0.6 sq m), and D (1.8 sq m) are incorrect as they do not align with the correct calculation of the surface area of the rectangular box.

Question 3 of 5

What is the result of adding 1/4 + 3/8?

Correct Answer: A

Rationale: To add 1/4 and 3/8, we need a common denominator, which is 8. So, 1/4 becomes 2/8. Adding 2/8 + 3/8 gives us 5/8. Therefore, the correct answer is A: 5/8. Choice B, 7/12, is incorrect as it is the result of adding 1/4 and 1/3. Choice C, 2/3, is incorrect as it is the result of adding 1/4 and 1/2. Choice D, 1/2, is incorrect as it is the result of adding 1/4 and 1/4.

Question 4 of 5

How many grams are in 10 kilograms?

Correct Answer: A

Rationale: To convert kilograms to grams, you need to multiply by 1000 since there are 1000 grams in 1 kilogram. So, to find the number of grams in 10 kilograms: 10 kilograms x 1000 = 10,000 grams. Therefore, the correct answer is A: 10,000 grams. The other choices are incorrect because they do not correctly convert 10 kilograms to grams. B: 100 grams is too small, C: 1000 grams is equivalent to 1 kilogram, and D: 100,000 grams is too large.

Question 5 of 5

A nurse works in the military hospital from 1300 to 2000. How many hours does this nurse work?

Correct Answer: C

Rationale: The nurse works from 1300 to 2000, which translates to 1 PM to 8 PM. To calculate the hours worked, subtract the start time from the end time: 8 PM - 1 PM = 7 hours. Therefore, the correct answer is C (7 hours). Choice A (8 hours) is incorrect as it includes the end time, Choice B (11 hours) is incorrect as it adds extra hours, and Choice D (12 hours) is incorrect as it adds both the start and end times.
