HESI A2 Practice Test Math Questions
Question 1 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 2 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
How many grams of carbohydrates are in a product if it contains 4 servings, and each serving has 8 grams of carbohydrates?
Correct Answer: A
Rationale: To calculate the total grams of carbohydrates in the product, you multiply the number of servings by the grams of carbohydrates per serving. In this case, 4 servings x 8 grams/serving = 32 grams of carbohydrates. Therefore, the correct answer is A. Explanation for other choices: B: 4 servings x 8 grams/serving does not equal 28 grams. C: 4 servings x 8 grams/serving does not equal 24 grams. D: 4 servings x 8 grams/serving does not equal 20 grams.
Question 5 of 5
There are 225 pieces of candy in a large jar. Ben wants to give the 25 campers in his group an equal amount of candy. How many pieces of candy will each camper receive?
Correct Answer: A
Rationale: To find the number of candies each camper will receive, divide the total number of candies (225) by the number of campers (25). 225 ÷ 25 = 9. Therefore, each camper will receive 9 pieces of candy. Choice A is correct because it correctly calculates the equal distribution. Choices B, C, and D are incorrect as they do not divide the total number of candies by the number of campers to determine the equal distribution.
