HESI A2 Math Practice

Correct Answer: A

Rationale: To find the distance traveled, we use the formula Distance = Speed x Time. In this case, the train's speed is 80 mph and it travels for 3 hours. So, Distance = 80 mph x 3 hours = 240 miles. Therefore, the correct answer is A: 240 miles. Option B (160 miles) is incorrect because it does not account for the full 3 hours of travel. Option C (280 miles) and Option D (320 miles) are incorrect as they are not the result of the correct calculation using the given speed and time values.

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.

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.

Correct Answer: A

Rationale: To express 0.025 as a ratio, we need to convert it to a fraction first. 0.025 as a fraction is 25/1000. Simplifying this gives us 1/40. Therefore, the correct ratio is 1:40. Choice A is correct as it represents the simplified form of 0.025 as a ratio. Choices B, C, and D are incorrect as they do not represent the equivalent simplified ratio of 0.025.

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.
