HESI A2 Math Practice Test 2023

Correct Answer: C

Rationale: To calculate the distance traveled, we use the formula Distance = Speed x Time. Given speed is 60 mph and time is 5 hours, we get Distance = 60 mph x 5 hours = 300 miles. Therefore, the correct answer is C. Option A is incorrect as it miscalculates the product of 60 x 5. Option B is incorrect as it is a lower value. Option D is a duplicate of option A and is also incorrect.

Correct Answer: C

Rationale: To convert gallons to ounces, we know that 1 gallon equals 128 ounces. Therefore, to find out how many ounces are in 2.5 gallons, we multiply 2.5 by 128. 2.5 * 128 = 320 ounces. Therefore, the correct answer is C: 320 ounces. Other choices are incorrect because they do not correctly calculate the conversion from gallons to ounces. A, B, and D do not consider the correct conversion factor of 128 ounces per gallon.

Correct Answer: A

Rationale: To convert the infant's weight from grams to pounds, divide 3,459 by 453.59 to get approximately 7.63 pounds. Since 1 pound is equal to 16 ounces, multiply the decimal part (.63) by 16 to get 10.08 ounces. Therefore, the infant's weight is 7 pounds and 10 ounces, making choice A the correct answer. Choices B, C, and D are incorrect due to incorrect conversions or calculations. B and C have the pound and ounce values switched, and D incorrectly converts the weight to 3 pounds and 13 ounces.

Correct Answer: D

Rationale: To convert 3/8 to a decimal, divide the numerator (3) by the denominator (8): 3 ÷ 8 = 0.375. The correct answer is D. Choice A (0.25) is the decimal equivalent of 1/4, not 3/8. Choice B is a duplicate of A. Choice C (0.3) is the decimal equivalent of 3/10, not 3/8.

Correct Answer: A

Rationale: The correct answer is A: 1/6. The probability of getting a 1 on a six-sided die is calculated by dividing the number of favorable outcomes (rolling a 1) by the total number of possible outcomes (6 sides on the die). Since there is only 1 side with a 1, the probability is 1/6. Choice B (1/4) is incorrect as it represents the probability of rolling a 1 on a four-sided die, which only has 4 sides. Choice C (1/3) is incorrect as it represents the probability of rolling a 1 on a three-sided die, which is not a standard die. Choice D (1/2) is incorrect as it represents the probability of rolling a 1 on a two-sided die, which is not a standard die.
