HESI A2 Math Practice Test 2023

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 add fractions with different denominators, first find a common denominator. In this case, the least common multiple of 8, 10, and 5 is 40. Then, convert each fraction to have a denominator of 40: 7/8 = 35/40, 9/10 = 36/40, and 6/5 = 24/40. Add them up to get 95/40 which simplifies to 2 & 15/40 = 3 & 3/8 = 3 & 39/40 (Choice A). Other choices are incorrect because they do not represent the correct sum of the fractions.

Correct Answer: A

Rationale: To convert yards to inches, you need to know that 1 yard is equal to 36 inches. Therefore, 1.5 yards is 1.5 x 36 = 54 inches. The correct answer is A (54 inches). Choice B (60 inches) is incorrect because it does not accurately convert 1.5 yards to inches. Choices C (72 inches) and D (84 inches) are also incorrect as they do not reflect the correct conversion.

Correct Answer: A

Rationale: To convert yards to inches, we know that 1 yard is equal to 36 inches. Therefore, 1.5 yards would be 1.5 x 36 = 54 inches. The correct answer is A (54 inches). Option B, 60 inches, is incorrect because it does not accurately convert 1.5 yards to inches. Option C, 72 inches, and option D, 84 inches, are also incorrect as they do not correctly represent the conversion from yards to inches in this scenario.

Correct Answer: C

Rationale: To convert gallons to ounces, we know that 1 gallon equals 128 ounces. Therefore, to find out how many ounces are in 2.5 gallons, we multiply 2.5 by 128. 2.5 * 128 = 320 ounces. Therefore, the correct answer is C: 320 ounces. Other choices are incorrect because they do not correctly calculate the conversion from gallons to ounces. A, B, and D do not consider the correct conversion factor of 128 ounces per gallon.
