Math HESI A2 Practice Test

Correct Answer: A

Rationale: To calculate 54% of $789.56, you multiply 789.56 by 0.54. This gives you $426.36, which is option A. The correct answer is A because multiplying the percentage (54%) by the total amount ($789.56) gives the accurate result. Option B, $426.37, is incorrect as it is a slightly higher amount due to rounding off. Option C, $363.20, and option D, $526.38, are incorrect because they are not the result of calculating 54% of $789.56 accurately.

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: B

Rationale: To convert 1/5 to a decimal, you divide 1 by 5. This gives you 0.2, which is the correct answer (B). Choice A (0.5) is the decimal equivalent of 1/2, not 1/5. Choice C (1.5) is the sum of 1 and 1/2. Choice D (0.15) is the decimal equivalent of 15/100, not 1/5. Therefore, the correct answer is B (0.2).

Correct Answer: B

Rationale: To solve for x in the equation 4x + 2 = 18, we first isolate x by subtracting 2 from both sides, giving us 4x = 16. Then, we divide both sides by 4 to find x = 4, which is choice B. The correct answer is x = 4 because substituting x = 4 back into the original equation gives 4(4) + 2 = 18, which simplifies to 16 + 2 = 18, confirming that x = 4 is the solution. Choices A, C, and D are incorrect because they do not satisfy the original equation when substituted back in.

Correct Answer: A

Rationale: To find the result of subtracting 4.7 from 9.5, we need to subtract 4.7 from 9.5. This can be calculated as 9.5 - 4.7 = 4.8. Therefore, the correct answer is A. Choice B (4.9) is incorrect because it is not the result of the subtraction operation provided in the question. Choice C (4.6) is incorrect because it is the result of subtracting 5.1 from 9.7, not 4.7 from 9.5. Choice D (4.7) is incorrect because it is the number being subtracted and not the final result of the subtraction.
