Math HESI A2 Practice Test

Correct Answer: B

Rationale: To divide 3.44 by 0.6, we perform the division as follows: 3.44 / 0.6 = 5.73 The correct answer is B. When dividing a decimal number by another decimal number, we move the decimal point in both numbers to make the divisor a whole number. Then we divide as usual. Choices A, C, and D are incorrect as they do not result from the correct division.

Correct Answer: D

Rationale: To convert ounces to pounds, divide the number of ounces by 16 (since there are 16 ounces in a pound). So, 128 ounces ÷ 16 = 8 pounds. Therefore, the correct answer is D: 8 pounds. A: 16 pounds - Incorrect, as 128 ounces is equivalent to 8 pounds. B: 10 pounds - Incorrect, as it does not result from the conversion of 128 ounces. C: 12 pounds - Incorrect, as it is not the accurate conversion from ounces to pounds.

Correct Answer: A

Rationale: To convert ounces to pounds, you divide the number of ounces by 16 since there are 16 ounces in a pound. Therefore, 160 ounces / 16 = 10 pounds. Choice A (10 pounds) is correct. Choices B, C, and D are incorrect because they do not correctly convert 160 ounces to pounds. Choice B is 8 pounds (160/16=10), Choice C is 5 pounds (160/16=10), and Choice D is 12 pounds (160/16=10).

Correct Answer: B

Rationale: To express 0.75 as a fraction, first note that 0.75 is equivalent to 75/100. Simplifying by dividing both the numerator and denominator by the greatest common divisor, which is 25, gives 3/4. Therefore, the correct answer is B: 3/4. Option A (4/5) is incorrect as it does not represent 0.75. Option C (1/2) is incorrect as it is not equal to 0.75. Option D (1/4) is incorrect as it is not the equivalent fraction of 0.75.

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.
