Math HESI A2 Practice Test

Correct Answer: B

Rationale: To change 0.26 to a fraction, we need to look at the decimal place. 0.26 can be written as 26/100, which can be simplified to 13/50 by dividing both the numerator and denominator by 2. This is the correct answer because it is in simplest form. Choice A is incorrect as 7/8 is not equivalent to 0.26. Choice C is incorrect as 26/100 is the initial form of 0.26, not simplified. Choice D is incorrect as 1/3 is not the equivalent fraction for 0.26.

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 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 convert milliliters to liters, we divide by 1000 since 1 liter = 1000 milliliters. So, 2500 milliliters ÷ 1000 = 2.5 liters. Therefore, the correct answer is A: 2.5 liters. Explanation for other choices: B: 1.5 liters - Incorrect, obtained by incorrect division. C: 3.5 liters - Incorrect, obtained by adding instead of dividing. D: 0.25 liters - Incorrect, obtained by misplaced decimal point.
