Math HESI A2 Practice Test

Correct Answer: A

Rationale: To convert ounces to pounds, you divide the number of ounces by 16 since there are 16 ounces in a pound. Therefore, 160 ounces / 16 = 10 pounds. Choice A (10 pounds) is correct. Choices B, C, and D are incorrect because they do not correctly convert 160 ounces to pounds. Choice B is 8 pounds (160/16=10), Choice C is 5 pounds (160/16=10), and Choice D is 12 pounds (160/16=10).

Correct Answer: A

Rationale: To add 3 1/8 and 1 1/4, first convert both to improper fractions: 3 1/8 = 25/8 and 1 1/4 = 5/4. Then, add the fractions: 25/8 + 5/4 = 50/8 + 10/8 = 60/8 = 7 1/2. Convert 7 1/2 back to a mixed number: 7 1/2 = 6 2/8 = 6 1/4 = 4 3/8, which is the correct answer (A). Choice B (4 1/2) is incorrect as it doesn't match the calculated sum. Choice C (4 3/4) is incorrect as it is not the simplified form of the sum. Choice D (5 1/4) is incorrect as it is higher than the calculated sum.

Correct Answer: B

Rationale: To find total calories consumed in 3 meals, multiply 500 calories/meal by 3 meals: 500 x 3 = 1500 calories. This is why choice B is correct. Choices A, C, and D are incorrect because they do not accurately calculate the total calories consumed in 3 meals. Choice A is half the correct answer, choice C is double, and choice D is the amount of calories in one meal, not for 3 meals.

Correct Answer: C

Rationale: To convert quarts to ounces, you need to know that 1 quart equals 32 ounces. Therefore, 1.5 quarts would be 1.5 x 32 = 48 ounces. So, the correct answer is C (48 ounces). Choice A is incorrect as it incorrectly converts quarts to ounces. Choice B is half of the correct conversion. Choice D is double the correct conversion.
