HESI A2 Practice Test Math

Correct Answer: A

Rationale: To convert a decimal to a percent, you multiply by 100. In this case, 0.98 * 100 = 98%. Therefore, the correct answer is A. Choice B is incorrect as it represents 9%, not 0.98%. Choice C is incorrect as it is the decimal form itself, not the percentage. Choice D is incorrect as it represents 99%, not 0.98%.

Correct Answer: B

Rationale: To convert ounces to pints, we know that 1 pint is equal to 16 ounces. Therefore, to find how many pints are in 56 ounces, we divide 56 by 16, which equals 3.5 pints. Hence, the correct answer is B: 3.5 pints. A: 3 pints - Incorrect. 56 ounces is more than 3 pints. C: 7 pints - Incorrect. 56 ounces equals 3.5 pints, not 7 pints. D: 8 pints - Incorrect. 56 ounces is less than 8 pints.

Correct Answer: A

Rationale: To subtract mixed numbers, first convert them to improper fractions. 30 1/2 = 61/2, and 13 3/4 = 55/4. Then subtract: 61/2 - 55/4 = 122/4 - 55/4 = 67/4 = 16 3/4 (A). Choices B, C, and D are incorrect because they do not represent the correct result of the subtraction calculation.

Correct Answer: B

Rationale: To find 20% of 150, you multiply 150 by 20% (or 0.20). So, 150 * 0.20 = 30. Therefore, the correct answer is B (30). Choice A (25) is incorrect because 20% of 150 is not 25. Choice C (35) is incorrect because it is more than 20% of 150. Choice D (20) is incorrect because 20% of 150 is not the same as the original number 150.

Correct Answer: A

Rationale: To find the full number, we can set up the equation: 0.30x = 18, where x is the full number. Solving for x, we get x = 18 / 0.30 = 60. Therefore, the correct answer is A (60). Choice B (30): 0.30 of 30 is 9, not 18. Choice C (40): 0.30 of 40 is 12, not 18. Choice D (45): 0.30 of 45 is 13.5, not 18.
