HESI A2 Math Practice Test 2023

Correct Answer: A

Rationale: To simplify -5 + (-8), we first add the two numbers together. -5 + (-8) = -13. The negative sign in front of 8 indicates that the number is negative. Therefore, the correct answer is A: -13. Choice B (8) and Choice D (-5) are incorrect because they do not account for the negative sign in front of the 8. Choice C (13) is incorrect as it is the result of adding the absolute values of -5 and -8 without considering the negative sign.

Correct Answer: A

Rationale: To determine the largest fraction, we need to find a common denominator. In this case, we can convert all fractions to have a denominator of 56. 3/7 = 24/56 3/6 = 28/56 3/9 = 21/56 3/8 = 21/56 Comparing the numerators, 28/56 is the largest, so the correct answer is 3/6 or option B. Option A (3/7) is incorrect as it is smaller than 3/6 when both are converted to a common denominator. Options C and D are also incorrect as they are smaller than option B.

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.

Correct Answer: A

Rationale: To subtract mixed numbers, first convert them to improper fractions. 12 1/8 = 97/8 and 9 1/2 = 19/2. Then, subtract the fractions: 97/8 - 19/2 = 97/8 - 38/8 = 59/8. Finally, convert the result back to a mixed number: 59/8 = 7 3/8. Therefore, the correct answer is A: 2 5/8. Choices B, C, and D are incorrect because they do not match the result of the subtraction calculation.

Correct Answer: D

Rationale: To convert ounces to pounds, we know that 1 pound is equal to 16 ounces. Therefore, to find how many pounds are in 144 ounces, we divide 144 by 16, which equals 9 pounds. The correct answer is D. Incorrect Answers: A: 12 pounds - Incorrect because 144 ounces is not equivalent to 12 pounds. B: 10 pounds - Incorrect, as 144 ounces do not convert to 10 pounds. C: 8 pounds - Incorrect, as 144 ounces do not equate to 8 pounds.
