Math HESI A2 Practice Test Questions
Question 1 of 5
Add: 3 1/8 + 1 1/4.
Correct Answer: A
Rationale: To add 3 1/8 and 1 1/4, first convert both to improper fractions: 3 1/8 = 25/8 and 1 1/4 = 5/4. Then, add the fractions: 25/8 + 5/4 = 50/8 + 10/8 = 60/8 = 7 1/2. Convert 7 1/2 back to a mixed number: 7 1/2 = 6 2/8 = 6 1/4 = 4 3/8, which is the correct answer (A). Choice B (4 1/2) is incorrect as it doesn't match the calculated sum. Choice C (4 3/4) is incorrect as it is not the simplified form of the sum. Choice D (5 1/4) is incorrect as it is higher than the calculated sum.
Question 2 of 5
A nurse works in the military hospital from 1300 to 2000. How many hours does this nurse work?
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.
Question 3 of 5
How many milliliters are in 6 liters?
Correct Answer: B
Rationale: To convert liters to milliliters, you need to multiply by 1000. Therefore, to find how many milliliters are in 6 liters, you would multiply 6 by 1000, which equals 6000 milliliters. Choice A (60 milliliters) is incorrect as it is 100 times less than the correct answer. Choice C (600 milliliters) is incorrect as it is 10 times less than the correct answer. Choice D (0.6 milliliters) is incorrect as it is a decimal and represents a fraction of the milliliters in 6 liters.
Question 4 of 5
What is the probability of rolling an even number on a six-sided die?
Correct Answer: A
Rationale: The correct answer is A: 50%. A six-sided die has 3 even numbers (2, 4, 6) out of a total of 6 possible outcomes (1, 2, 3, 4, 5, 6). To calculate the probability of rolling an even number, we divide the number of favorable outcomes (3) by the total number of outcomes (6), resulting in 3/6 = 0.5 or 50%. Explanation of other choices: B: 16.70% - Incorrect. This percentage does not represent the probability of rolling an even number on a six-sided die. C: 25% - Incorrect. This represents the probability of rolling any number divisible by 5 on a six-sided die, not just even numbers. D: 33.30% - Incorrect. This percentage does not reflect the probability of rolling an even number on a six-sided die.
Question 5 of 5
How many pounds are in 48 ounces?
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.
