HESI A2 Math Practice Test 2023

Correct Answer: C

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 4.5 quarts, we multiply 4.5 by 32, which equals 144 ounces. So, the correct answer is C (144 ounces). Incorrect Choices: A: 120 ounces - This is incorrect because it does not account for the correct conversion factor of 1 quart to 32 ounces. B: 120 ounces - Same as choice A, incorrect conversion factor used. D: 128 ounces - This is incorrect as it is not the correct result of multiplying 4.5 quarts by 32 ounces per quart.

Correct Answer: A

Rationale: To change 0.004 to a ratio, we need to express it as a fraction. 0.004 as a fraction is 4/1000, which simplifies to 1/250. Therefore, the correct ratio is 1:250. Choice A is correct because it accurately represents the ratio of 0.004. Choices B, C, and D are incorrect because they do not accurately reflect the equivalent ratio for 0.004.

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 millimeters to meters, we divide by 1000 since there are 1000 millimeters in a meter. Therefore, 3000 millimeters divided by 1000 equals 3 meters. Choice A is correct. Choices B, C, and D are incorrect because they do not correctly convert millimeters to meters. Choice B is 30 times the correct answer, choice C is 10 times less, and choice D is 100 times more.

Correct Answer: B

Rationale: To find the sum of 1/3, 1/4, and 1/6, we need to first find a common denominator, which is 12 in this case. Then, we convert each fraction to have the same denominator: 1/3 = 4/12, 1/4 = 3/12, and 1/6 = 2/12. Adding these fractions gives us 4/12 + 3/12 + 2/12 = 9/12, which simplifies to 3/4 or 0.75. Therefore, the correct answer is B: 1/2. Explanation for other choices: A: 5/12 - Incorrect. This sum is not equal to the sum of 1/3, 1/4, and 1/6. C: 1/3 - Incorrect. This is the value of just one of the given fractions, not the sum of all three
