HESI A2 Math Practice Exam

Correct Answer: B

Rationale: To convert pints to ounces, we know that 1 pint is equal to 16 ounces. Therefore, 3 pints would be 3 x 16 = 48 ounces. This makes choice B the correct answer. Choice A (24 ounces) is incorrect as it represents only 1 pint, not 3. Choice C (32 ounces) and choice D (64 ounces) are also incorrect as they do not accurately reflect the conversion of pints to ounces.

Correct Answer: C

Rationale: To calculate the total area to paint, we need to find the surface area of the walls and the floor separately. The surface area of the walls is 2*(8+5)*2 = 36 sq m. The floor area is 8*5 = 40 sq m. Adding these together gives 36 + 40 = 76 sq m. Since one can of paint covers 10 sq m, we need 76/10 = 7.6 cans of paint. Rounding up to the nearest whole number, we need 8 cans of paint, which is equivalent to 88 sq m. Therefore, the correct answer is C (88 sq m). Choice A (56 sq m) is incorrect as it does not consider the surface area of the floor. Choice B (72 sq m) is incorrect as it miscalculates the total area to paint. Choice D (104 sq m) is incorrect as it overestimates the amount of paint needed.

Correct Answer: A

Rationale: To add 1.332 and 0.067, start from the rightmost digit and move left. Add 2 + 7 (9), then 3 + 6 (9), and 1 + 0 (1). The sum is 1.399, making choice A the correct answer. Choices B, C, and D are incorrect as they do not match the correct sum obtained through the addition process.

Correct Answer: B

Rationale: To calculate the number of tablets needed: 1. Determine the total dosage needed: 16 mg/kg x 15 kg = 240 mg. 2. Divide the total dosage by the dosage per tablet: 240 mg ÷ 80 mg = 3 tablets. 3. The correct answer is B (2 tablets) as it is the nearest whole number to the calculated 3 tablets. Choice A is incorrect because it is less than the calculated amount. Choice C is incorrect as it is less than the required dosage. Choice D is incorrect as it is a non-integer value.

Correct Answer: A

Rationale: Certainly! To compare, we need to convert both fractions to a common denominator. LCM of 8 and 100 (8*25) is 100. Sally ate (5/8)*100 = 62.5%. John ate 75%. Clearly, 75% is more than 62.5%. So, John ate more. Other choices are incorrect as they do not consider the actual percentages consumed by Sally and John.
