HESI A2 Math Practice Test 2023

Correct Answer: C

Rationale: To convert milliliters to liters, you need to divide by 1,000 since there are 1,000 milliliters in 1 liter. So, 2,000 milliliters divided by 1,000 equals 2 liters. Therefore, the correct answer is C: 2 liters. Choice A is incorrect as it incorrectly doubles the conversion factor. Choice B is incorrect as it doesn't account for the conversion from milliliters to liters. Choice D is incorrect as it duplicates choice A.

Correct Answer: B

Rationale: To convert milliliters to liters, you divide by 1000 since 1 liter is equal to 1000 milliliters. So, 8000 milliliters divided by 1000 equals 8 liters. Therefore, the correct answer is B: 8 liters. Explanation for incorrect choices: A: 0.8 liters - Incorrect because the conversion is 8000 milliliters divided by 1000 equals 8 liters, not 0.8 liters. C: 0.8 liters - Same as choice A, incorrect conversion. D: 0.08 liters - Incorrect because the conversion is 8000 milliliters divided by 1000 equals 8 liters, not 0.08 liters.

Correct Answer: B

Rationale: To find the perimeter of the table, we add the lengths of all four sides. Since opposite sides are equal, we have two pairs of sides with lengths 75cm and 50cm each. Therefore, the perimeter is 2(75cm) + 2(50cm) = 150cm. Choice A is incorrect because it only considers one pair of sides. Choice C is incorrect as it adds all sides together without considering the pairs. Choice D is incorrect as it only considers one side length.

Correct Answer: A

Rationale: To determine the largest fraction, we need to find a common denominator. In this case, we can convert all fractions to have a denominator of 56. 3/7 = 24/56 3/6 = 28/56 3/9 = 21/56 3/8 = 21/56 Comparing the numerators, 28/56 is the largest, so the correct answer is 3/6 or option B. Option A (3/7) is incorrect as it is smaller than 3/6 when both are converted to a common denominator. Options C and D are also incorrect as they are smaller than option B.

Correct Answer: B

Rationale: To convert quarts to ounces, we know that 1 quart is equal to 32 ounces. Therefore, to find out how many ounces are in 4 quarts, we multiply 4 (quarts) by 32 (ounces/quart), which equals 128 ounces. Thus, the correct answer is B: 128 ounces. A: 64 ounces - Incorrect, this is the equivalent of 2 quarts, not 4. C: 32 ounces - Incorrect, this is the equivalent of 1 quart, not 4. D: 16 ounces - Incorrect, this is half the amount of 1 quart, not 4.
