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
Convert 26°C to Fahrenheit.
Correct Answer: A
Rationale:
To convert Celsius to Fahrenheit, the formula F = (9/5)C + 32 is used. Substituting 26°C into the formula: F = (9/5)(26) + 32 = 78.8°F, which rounds to 78°F.
Therefore, the correct answer is 78°F.
Choice B (72°F),
Choice C (80°F), and
Choice D (85°F) are incorrect as they do not result from the correct conversion calculation.
Question 3 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 4 of 5
How many gallons are in 576 fluid ounces?
Correct Answer: A
Rationale:
To convert fluid ounces to gallons, you need to know that there are 128 fluid ounces in a gallon.
To find how many gallons are in 576 fluid ounces, divide 576 by 128, which equals 4.5 gallons. Since we are looking for the closest whole number, the answer is 4 gallons.
Choice A is correct.
Choice B, C, and D are incorrect as they do not accurately represent the conversion from fluid ounces to gallons.
Question 5 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.
