HESI A2 Math Practice Exam Questions

Question 1 of 5

Convert 5 3/4 to a decimal. Round to the nearest tenth.

Correct Answer: C

Rationale: To convert 5 3/4 to a decimal, first convert the mixed number to an improper fraction: 5 3/4 = (4*5 + 3)/4 = 23/4. Then, divide the numerator by the denominator to get the decimal: 23 ÷ 4 = 5.75. Rounding to the nearest tenth gives 5.8, which is choice C. Choices A, B, and D are incorrect because they do not accurately represent the decimal equivalent of 5 3/4 rounded to the nearest tenth.

Question 2 of 5

How many millimeters are in 5 meters?

Correct Answer: A

Rationale: To convert meters to millimeters, we know that 1 meter is equal to 1000 millimeters. Therefore, to find how many millimeters are in 5 meters, we multiply 5 by 1000 which equals 5000 millimeters. Choice A (5000 mm) is correct. Choices B, C, and D are incorrect as they do not accurately convert 5 meters to millimeters. Choice B (4000 mm) is incorrect because it underestimates the conversion. Choice C (5500 mm) is incorrect as it overestimates the conversion. Choice D (6000 mm) is also incorrect as it overestimates the conversion.

Question 3 of 5

If 9 out of 75 band members missed practice, what percentage of band members missed practice?

Correct Answer: B

Rationale: To find the percentage of band members who missed practice, we need to calculate the ratio of band members who missed practice to the total band members. 9 out of 75 band members missed practice, so the ratio is 9/75 = 0.12 or 12%. Therefore, the correct answer is B (12%). Choice A (10%) is incorrect as 9 out of 75 is not equivalent to 10%. Choice C (15%) is incorrect as 9 out of 75 is not equivalent to 15%. Choice D (18%) is incorrect as 9 out of 75 is not equivalent to 18%.

Question 4 of 5

What is the average of the numbers 14, 73, and 7?

Correct Answer: D

Rationale: To find the average of a set of numbers, you add them up and then divide by the total number of values. In this case, 14 + 73 + 7 = 94. Then, 94 divided by 3 (total numbers) gives 31.33. Therefore, choice D is correct. Choices A, B, and C are incorrect because they do not correctly calculate the average of the given numbers. A, B, and C are calculated as 14 + 73 + 7 divided by 3, which leads to incorrect averages.

Question 5 of 5

A baseball team won 72 games. This was 90% of the games it played. How many games did it play?

Correct Answer: B

Rationale: To find the total number of games played, we divide the number of games won (72) by the percentage of games won (90%). This gives us 72 / 0.90 = 80 games played. Therefore, choice B is correct. Choice A (75) is incorrect because it does not account for the percentage of games won. Choice C (85) is incorrect as it overestimates the total number of games played. Choice D (100) is incorrect as it does not reflect the fact that the team won only 90% of the games played.
