HESI A2 Math Practice Questions
Question 1 of 5
How many pounds are in 80 ounces?
Correct Answer: A
Rationale: To convert ounces to pounds, we need to know that 1 pound is equal to 16 ounces. Given 80 ounces, dividing by 16 gives 5 pounds. Therefore, the correct answer is A: 5 pounds. Choice B is incorrect because it is too high, choice C is incorrect as it is too low, and choice D is also too low.
Question 2 of 5
What is the probability of rolling a 3 on a six-sided die?
Correct Answer: A
Rationale: The correct answer is A: 1/6. There is only one face on a six-sided die that shows a 3, so the probability of rolling a 3 is 1 out of 6 possible outcomes (1, 2, 3, 4, 5, 6). To calculate the probability, divide the favorable outcomes (1) by the total possible outcomes (6), which gives 1/6. Summary: B: 1/4 - Incorrect, as there is only one 3 on a six-sided die, not 1 out of 4. C: 1/3 - Incorrect, as the probability of rolling a 3 is 1 out of 6, not 1 out of 3. D: 1/2 - Incorrect, as only one face represents a 3, not half of the faces on a six-sided die.
Question 3 of 5
What is the probability of rolling an odd number on a six-sided die?
Correct Answer: A
Rationale: The correct answer is A (50%). There are 3 odd numbers (1, 3, 5) on a six-sided die out of a total of 6 possible outcomes (1, 2, 3, 4, 5, 6). To calculate the probability, you divide the number of favorable outcomes (3) by the total number of outcomes (6), which equals 0.5 or 50%. Choice B (66.70%) is incorrect because it assumes there are 4 odd numbers out of 6, which is not the case. Choice C (33.30%) is incorrect because it calculates the probability of rolling an even number. Choice D (25%) is incorrect as it represents the probability of rolling a specific number (1) out of 6 possible outcomes.
Question 4 of 5
How many inches are in 3.5 yards?
Correct Answer: A
Rationale: To convert yards to inches, we use the fact that 1 yard is equal to 36 inches. Therefore, to find how many inches are in 3.5 yards, we multiply 3.5 by 36, which equals 126 inches. Choice A (126 inches) is correct. Choices B, C, and D are incorrect as they do not correctly calculate the conversion from yards to inches. B (144 inches) is the result of multiplying 3.5 by 40 instead of 36. C (132 inches) is the result of multiplying 3.5 by 38. D (120 inches) is the result of multiplying 3.5 by 34.
Question 5 of 5
Multiply: 4/9 1 4/5 2/5.
Correct Answer: A
Rationale: To multiply the fractions, first convert the mixed number to an improper fraction: 1 4/5 = 9/5. Then, multiply all fractions: (4/9) * (9/5) * (2/5) = 8/25. Therefore, choice A (8/25) is the correct answer. Choices B, C, and D are incorrect because they do not match the result of the multiplication.
