HESI A2 Math Practice Questions
Question 1 of 5
Multiply: 3/4 1/3.
Correct Answer: A
Rationale: To multiply fractions, multiply the numerators (top numbers) and denominators (bottom numbers) separately. So, 3/4 * 1/3 = (3*1) / (4*3) = 3/12 = 1/4. Therefore, the correct answer is A. Choice B is incorrect because multiplying the numerators and denominators would give 3/12, not 1/3. Choice C is incorrect as the result of multiplying 3/4 and 1/3 is 1/4, not 3/5. Choice D is incorrect as 3/4 * 1/3 is 1/4, not 3/8.
Question 2 of 5
Multiply: 3/4 1/3.
Correct Answer: A
Rationale: To multiply fractions, multiply the numerators (top numbers) and denominators (bottom numbers) separately. So, 3/4 * 1/3 = (3*1) / (4*3) = 3/12 = 1/4. Therefore, the correct answer is A. Choice B is incorrect because multiplying the numerators and denominators would give 3/12, not 1/3. Choice C is incorrect as the result of multiplying 3/4 and 1/3 is 1/4, not 3/5. Choice D is incorrect as 3/4 * 1/3 is 1/4, not 3/8.
Question 3 of 5
How many ounces are in 2.5 quarts?
Correct Answer: D
Rationale: To convert quarts to ounces, we know that 1 quart is equal to 32 ounces. Therefore, to find out how many ounces are in 2.5 quarts, we multiply 2.5 by 32 which gives us 80 ounces. So, the correct answer is D. Choices A, B, and C are incorrect because they do not accurately represent the conversion from quarts to ounces. Choice A (64 ounces) is the equivalent of 2 quarts, choice B (40 ounces) is the equivalent of 1.25 quarts, and choice C (32 ounces) is the equivalent of 1 quart.
Question 4 of 5
Solve: 8x = x^2.
Correct Answer: C
Rationale: To solve 8x = x^2, we rearrange the equation to x^2 - 8x = 0. Factoring gives x(x-8) = 0. So, x = 0 or x = 8. Therefore, the correct answer is C (16). Choices A, B, D are incorrect as they do not satisfy the equation x^2 = 8x.
Question 5 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.
