Math HESI A2 Practice Test

Correct Answer: A

Rationale: To convert ounces to pounds, we divide by 16 (since 1 pound = 16 ounces). Therefore, 48 ounces ÷ 16 = 3 pounds. So, the correct answer is A: 3 lbs. Choice B, 6 lbs, is incorrect as it would be 48 ounces ÷ 8 (not 16). Choice C, 4 lbs, and choice D, 8 lbs, are also incorrect based on the conversion factor of 1 pound = 16 ounces.

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: The correct answer is A: 1/6. There is only one outcome of rolling a 2 on a six-sided die, and there are a total of six possible outcomes (1, 2, 3, 4, 5, 6). Therefore, the probability of rolling a 2 is 1 out of 6, which simplifies to 1/6. Explanation for why other choices are incorrect: B: 1/4 - This is incorrect because there is only one outcome of rolling a 2, not 2 outcomes out of 6. C: 1/3 - This is incorrect because the probability of rolling a 2 is not 1 out of 3, but 1 out of 6. D: 1/2 - This is incorrect because the probability of rolling a 2 is not 1 out of 2, but 1 out of 6.

Correct Answer: B

Rationale: To divide 3.44 by 0.6, we perform the division as follows: 3.44 / 0.6 = 5.73 The correct answer is B. When dividing a decimal number by another decimal number, we move the decimal point in both numbers to make the divisor a whole number. Then we divide as usual. Choices A, C, and D are incorrect as they do not result from the correct division.

Correct Answer: A

Rationale: To convert 5/8 to a decimal, divide 5 by 8, which equals 0.625. The correct answer is A (0.625) because it is the result of dividing the numerator by the denominator. Choice B (0.5) is incorrect as 5/8 is not equal to 0.5. Choice C (0.4) and choice D (0.75) are also incorrect as they do not represent the equivalent decimal value of 5/8.
