HESI A2 Math Practice Test 2023

Correct Answer: D

Rationale: To find 80% of $500, you multiply $500 by 0.80. 0.80 represents 80% in decimal form. So, $500 x 0.80 = $400. Choice D is correct. Choice A is incorrect because $425 is 85% of $500. Choice B is incorrect because $450 is 90% of $500. Choice C is incorrect because $350 is 70% of $500.

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: 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 milliliters to liters, we need to divide by 1000 since there are 1000 milliliters in a liter. So, 300 milliliters ÷ 1000 = 0.3 liters. Therefore, the correct answer is A: 0.3 liters. Explanation for other choices: B: 3 liters - Incorrect, as 300 milliliters is not equal to 3 liters. C: 0.03 liters - Incorrect, the decimal point placement is off. D: 3.3 liters - Incorrect, as it is not the correct conversion from milliliters to liters.

Correct Answer: D

Rationale: To convert ounces to pounds, we know that 1 pound is equal to 16 ounces. Therefore, to find how many pounds are in 144 ounces, we divide 144 by 16, which equals 9 pounds. The correct answer is D. Incorrect Answers: A: 12 pounds - Incorrect because 144 ounces is not equivalent to 12 pounds. B: 10 pounds - Incorrect, as 144 ounces do not convert to 10 pounds. C: 8 pounds - Incorrect, as 144 ounces do not equate to 8 pounds.
