Math HESI A2 Practice Test

Correct Answer: D

Rationale: To convert quarts to ounces, we know that 1 quart equals 32 ounces. Therefore, 3 quarts would equal 3 x 32 = 96 ounces. This makes answer choice D (96 ounces) the correct option. Choice A (64 ounces) is incorrect because it miscalculates the conversion. Choice B (32 ounces) is incorrect as it represents 1 quart, not 3 quarts. Choice C (48 ounces) is also incorrect as it is an intermediate value between the correct answer and the incorrect answer A.

Correct Answer: B

Rationale: To express 0.75 as a fraction, first note that 0.75 is equivalent to 75/100. Simplifying by dividing both the numerator and denominator by the greatest common divisor, which is 25, gives 3/4. Therefore, the correct answer is B: 3/4. Option A (4/5) is incorrect as it does not represent 0.75. Option C (1/2) is incorrect as it is not equal to 0.75. Option D (1/4) is incorrect as it is not the equivalent fraction of 0.75.

Correct Answer: A

Rationale: To produce 6 eggs in 24 hours, 2 chickens are needed. Therefore, to produce 24 eggs, we need (2 chickens / 6 eggs) * 24 eggs = 8 chickens. So, the correct answer is A. Choice B is incorrect because it does not account for the correct ratio of chickens to eggs. Choice C is incorrect as it overestimates the number of chickens needed. Choice D is incorrect as it does not consider the ratio of chickens to eggs accurately.

Correct Answer: B

Rationale: The correct answer is B: Decimal. The decimal number system is commonly used in the United States because it is based on powers of 10, making it easy for people to understand and use in everyday life, such as in currency, measurements, and calculations. Tertiary and Napoleonic number systems are not commonly used in the United States. Binary is a base-2 number system, which is used in computer science but not as widely used in everyday life in the US.

Correct Answer: C

Rationale: To find the total words typed in 20 minutes, multiply words per minute by minutes: 45 words/minute x 20 minutes = 900 words. Thus, the correct answer is C (900 words). A is incorrect as it miscalculates the total. B is incorrect as it underestimates the total. D is incorrect as it duplicates option A.
