Math HESI A2 Practice Test

Correct Answer: D

Rationale: To convert ounces to pounds, divide the number of ounces by 16 (since there are 16 ounces in a pound). So, 128 ounces ÷ 16 = 8 pounds. Therefore, the correct answer is D: 8 pounds. A: 16 pounds - Incorrect, as 128 ounces is equivalent to 8 pounds. B: 10 pounds - Incorrect, as it does not result from the conversion of 128 ounces. C: 12 pounds - Incorrect, as it is not the accurate conversion from ounces to pounds.

Correct Answer: C

Rationale: To convert kilometers to meters, we need to multiply the number of kilometers by 1000 since there are 1000 meters in 1 kilometer. So, 2 kilometers x 1000 meters/kilometer = 2000 meters. Therefore, the correct answer is C: 2000 meters. Choice A (100 meters) is incorrect as it does not account for the conversion factor of 1000 meters in 1 kilometer. Choice B (200 meters) is incorrect for the same reason. Choice D (3000 meters) is incorrect as it goes beyond the actual conversion calculation.

Correct Answer: A

Rationale: To convert milliliters to liters, we divide by 1000 since 1 liter = 1000 milliliters. So, 2500 milliliters ÷ 1000 = 2.5 liters. Therefore, the correct answer is A: 2.5 liters. Explanation for other choices: B: 1.5 liters - Incorrect, obtained by incorrect division. C: 3.5 liters - Incorrect, obtained by adding instead of dividing. D: 0.25 liters - Incorrect, obtained by misplaced decimal point.

Correct Answer: A

Rationale: The correct answer is A: 50%. A six-sided die has 3 even numbers (2, 4, 6) out of a total of 6 possible outcomes (1, 2, 3, 4, 5, 6). To calculate the probability of rolling an even number, we divide the number of favorable outcomes (3) by the total number of outcomes (6), resulting in 3/6 = 0.5 or 50%. Explanation of other choices: B: 16.70% - Incorrect. This percentage does not represent the probability of rolling an even number on a six-sided die. C: 25% - Incorrect. This represents the probability of rolling any number divisible by 5 on a six-sided die, not just even numbers. D: 33.30% - Incorrect. This percentage does not reflect the probability of rolling an even number on a six-sided die.

Correct Answer: A

Rationale: To calculate 54% of $789.56, you multiply 789.56 by 0.54. This gives you $426.36, which is option A. The correct answer is A because multiplying the percentage (54%) by the total amount ($789.56) gives the accurate result. Option B, $426.37, is incorrect as it is a slightly higher amount due to rounding off. Option C, $363.20, and option D, $526.38, are incorrect because they are not the result of calculating 54% of $789.56 accurately.
