HESI A2 Practice Test Math Questions
Question 1 of 5
What is the result of adding 5 2/9 and 1 2/9?
Correct Answer: A
Rationale: To add 5 2/9 and 1 2/9, first add the whole numbers: 5 + 1 = 6. Then add the fractions: 2/9 + 2/9 = 4/9. Combine the whole number and the fraction to get 6 4/9, which is the correct answer (A). Other choices are incorrect because they either do not consider adding the fractions (D), or incorrectly add only the whole numbers (C), or miscalculate the fractions (B).
Question 2 of 5
A teacher's aide is preparing a snack for the class. In order to prepare the powdered drink, the aide must convert the directions to metric. The directions say, 'Dilute contents of package in 2 quarts of water.' The aide has a measuring device marked in liters. How many liters of water should be used?
Correct Answer: A
Rationale: The correct answer is A: 2 liters. 1 quart is equivalent to 0.946 liters. Therefore, 2 quarts equal 1.892 liters, which can be rounded to 2 liters for practical purposes. This conversion is necessary as the measuring device is marked in liters, and the directions in quarts need to be converted accurately. The other choices are incorrect because B (1 liter) is less than the required amount, C (3 liters) is too much, and D (5 liters) is excessive based on the conversion from quarts to liters.
Question 3 of 5
A label states 1 mil contains 500 mg. How many mils are there if there are 1.5 grams?
Correct Answer: C
Rationale: To calculate the number of mils in 1.5 grams, we first convert 1.5 grams to milligrams: 1.5g * 1000mg/g = 1500mg. Then, we divide 1500mg by the amount in 1 mil (500mg/mil) to get 3 mils. Choice C is correct. Choices A, B, and D are incorrect because they do not follow the correct conversion process. Choice A (9 mils) results from dividing 1500mg by 500mg, which is incorrect. Choice B (2 mils) and Choice D (5 mils) also do not yield the correct answer when dividing 1500mg by 500mg.
Question 4 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: To convert ounces to milliliters, we use the conversion factor: 1 oz = 29.5735 mL. Since the bottle contains 1/2 oz, we multiply 1/2 by 29.5735 to get 14.78675 mL. Rounding up, the closest option is 15 mL (choice A). Choices B, C, and D are incorrect as they do not match the calculated conversion from ounces to milliliters.
Question 5 of 5
How many gallons are in 576 fluid ounces?
Correct Answer: A
Rationale: To convert fluid ounces to gallons, we know that 1 gallon equals 128 fluid ounces. Therefore, to find how many gallons are in 576 fluid ounces, we divide 576 by 128, which equals 4. So, the correct answer is A: 4 gallons. Option B (5 gallons) is incorrect because the conversion calculation shows that 576 fluid ounces is equivalent to 4 gallons, not 5 gallons. Option C (6 gallons) is incorrect as well, as 576 fluid ounces is less than 6 gallons. Option D (3 gallons) is incorrect because the conversion calculation clearly demonstrates that 576 fluid ounces is equal to 4 gallons, not 3 gallons.
