HESI A2 Practice Test Math Questions
Question 1 of 5
In a class of 25 students, 44% are boys. How many boys are there?
Correct Answer: B
Rationale:
To find the number of boys in the class, calculate 44% of 25 students. 44% of 25 is calculated as follows: 0.44 x 25 = 11 boys.
Therefore, there are 11 boys in the class.
Choice A, 10 boys, is incorrect as it miscalculates the percentage.
Choice C, 9 boys, is incorrect as it is less than 11.
Choice D, 13 boys, is incorrect as it is greater than the correct calculation.
Question 2 of 5
What is 39 · 8 · 7/6?
Correct Answer: A
Rationale:
To solve the division problem, we need to remember the rule 'Dividing by a fraction is the same as multiplying by its reciprocal.'
Therefore, 39 · 8 · 7/6 is equivalent to 39 · 8 6/7. Simplifying this gives (39 6) · (8 7) = 234 · 56 = 56/39.
Therefore, the correct answer is A.
Choices B, C, and D are incorrect as they do not correctly simplify the given division problem.
Question 3 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 4 of 5
What is the result of dividing 40.3 by 4.8?
Correct Answer: B
Rationale:
To divide 40.3 by 4.8, you perform the calculation: 40.3 · 4.8 ≈ 8.4.
Therefore, the correct answer is 8.4.
Choice A (7.5) is incorrect as it is the result of dividing 40.3 by 5.4.
Choice C (6.2) is incorrect as it is the result of dividing 40.3 by 6.5.
Choice D (9.1) is incorrect as it is the result of dividing 40.3 by 4.4.
Question 5 of 5
A female ran a 24-mile course. Her first 6 miles she ran in 1 hour. The second set of 6 miles in 1.2 hours. The third set of 6 miles in 1.5 hours. The fourth set of 6 miles in 1.6 hours. How long did it take her to complete the course?
Correct Answer: B
Rationale:
To find the total time, add the times for each set of 6 miles: 1 + 1.2 + 1.5 + 1.6 = 5.3 hours.
Therefore, it took her 5.3 hours to complete the 24-mile course.
Choice A, 5 hours, is incorrect because the total time is slightly more than that.
Choice C, 4 hours, is incorrect as it doesn't account for the total time taken.
Choice D, 6 hours, is incorrect as it's an overestimation of the actual time taken.
