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: C

Rationale: The nurse works from 1300 to 2000, which translates to 1 PM to 8 PM. To calculate the hours worked, subtract the start time from the end time: 8 PM - 1 PM = 7 hours. Therefore, the correct answer is C (7 hours). Choice A (8 hours) is incorrect as it includes the end time, Choice B (11 hours) is incorrect as it adds extra hours, and Choice D (12 hours) is incorrect as it adds both the start and end times.

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.

Correct Answer: B

Rationale: To convert pints to ounces, we know that 1 pint is equal to 16 ounces. Therefore, 8 1/4 pints can be calculated as 8 x 16 + 4 = 132 ounces. This is why choice B (132 oz) is correct. Choices A, C, and D are incorrect because they do not accurately represent the conversion of pints to ounces in this scenario.

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.
