HESI A2 Math Practice Test 2023

Correct Answer: A

Rationale: To determine the distance traveled by the train, we use the formula Distance = Speed x Time. Given the speed of 65 mph and time of 1.5 hours, we calculate 65 mph x 1.5 hours = 97.5 miles. Therefore, the correct answer is A: 97.5 miles. Option B, 100 miles, is incorrect as it does not match the calculated result. Options C and D, 98 miles and 95 miles, respectively, are also incorrect as they do not align with the calculated distance based on the given speed and time.

Correct Answer: B

Rationale: To convert grams to milligrams, you multiply by 1000 since there are 1000 milligrams in 1 gram. Therefore, 7 grams x 1000 = 7000 milligrams, which corresponds to choice B. Choice A is incorrect as it represents 700 mg (not 7000 mg). Choice C is incorrect as it represents 70 mg (not 7000 mg). Choice D is incorrect as it represents 0.007 mg (not 7000 mg).

Correct Answer: A

Rationale: To convert 0.25 to a fraction, recognize that 0.25 is equivalent to 25/100, which simplifies to 1/4 when both the numerator and denominator are divided by their greatest common factor, which is 25. Therefore, the correct answer is A: 1/4. Choice B (1/3) and Choice C (1/2) are incorrect because they do not equal 0.25. Choice D (3/4) is incorrect as it is the reverse of the correct answer.

Correct Answer: A

Rationale: To convert pints to milliliters, we need to know that 1 pint = 473.176 milliliters. Therefore, 5 pints would be 5 x 473.176 = 2365.88 milliliters. Rounding up, we get approximately 2400 milliliters. This is why choice A (2400 milliliters) is correct. Choices B, C, and D are incorrect because they do not accurately convert pints to milliliters based on the conversion factor provided.
