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: A

Rationale: To divide 5 3/4 by 1/2, we convert 5 3/4 to an improper fraction as 23/4. Then, we divide 23/4 by 1/2, which is equivalent to multiplying by the reciprocal of 1/2, which is 2. Therefore, 23/4 * 2 = 46/4 = 11 1/2. The correct answer is A. Other choices are incorrect as they do not result from the correct calculation process.

Correct Answer: B

Rationale: To convert liters to milliliters, you need to know that 1 liter is equal to 1000 milliliters. Therefore, to find how many milliliters are in 3 liters, you would multiply 3 by 1000, which equals 3000 milliliters. So, the correct answer is B: 3000 milliliters. A is incorrect because it is the result of multiplying 3 by 100, not 1000. C is incorrect because it is half of 3000, not the actual conversion. D is incorrect as it is one-tenth of the correct answer.

Correct Answer: D

Rationale: To find 75% of 80, you multiply 80 by 0.75 (which represents 75%). 80 * 0.75 = 60. Therefore, the correct answer is D: 60. Choice A (35) is incorrect because it is not 75% of 80. Choice B (45) is also incorrect as it is not the correct calculation for 75% of 80. Choice C (70) is incorrect as well since it does not represent 75% of 80.

Correct Answer: A

Rationale: To add 3 1/8 and 1 1/4, first convert both to improper fractions: 3 1/8 = 25/8 and 1 1/4 = 5/4. Then, add the fractions: 25/8 + 5/4 = 50/8 + 10/8 = 60/8 = 7 1/2. Convert 7 1/2 back to a mixed number: 7 1/2 = 6 2/8 = 6 1/4 = 4 3/8, which is the correct answer (A). Choice B (4 1/2) is incorrect as it doesn't match the calculated sum. Choice C (4 3/4) is incorrect as it is not the simplified form of the sum. Choice D (5 1/4) is incorrect as it is higher than the calculated sum.
