Math HESI A2 Practice Test Questions

Question 1 of 5

What is the result of dividing 5 3/4 by 1/2?

Correct Answer: A

Rationale: To divide 5 3/4 by 1/2, we convert 5 3/4 to an improper fraction as 23/4. Then, we divide 23/4 by 1/2, which is equivalent to multiplying by the reciprocal of 1/2, which is 2. Therefore, 23/4 * 2 = 46/4 = 11 1/2. The correct answer is A. Other choices are incorrect as they do not result from the correct calculation process.

Question 2 of 5

How many milligrams are in 7 grams?

Correct Answer: A

Rationale: To convert grams to milligrams, you multiply by 1000 since there are 1000 milligrams in a gram. So, 7 grams x 1000 = 7000 mg. Therefore, the correct answer is A: 7000 mg. Option B (7 mg) is incorrect because it represents the original unit (grams). Option C (700 mg) is incorrect as it is a partial conversion error. Option D (70 mg) is incorrect as it is a multiple of 10 error.

Question 3 of 5

How many meters are in 2 kilometers?

Correct Answer: C

Rationale: To convert kilometers to meters, we need to multiply the number of kilometers by 1000 since there are 1000 meters in 1 kilometer. So, 2 kilometers x 1000 meters/kilometer = 2000 meters. Therefore, the correct answer is C: 2000 meters. Choice A (100 meters) is incorrect as it does not account for the conversion factor of 1000 meters in 1 kilometer. Choice B (200 meters) is incorrect for the same reason. Choice D (3000 meters) is incorrect as it goes beyond the actual conversion calculation.

Question 4 of 5

What is 54% of $789.56?

Correct Answer: A

Rationale: To calculate 54% of $789.56, you multiply 789.56 by 0.54. This gives you $426.36, which is option A. The correct answer is A because multiplying the percentage (54%) by the total amount ($789.56) gives the accurate result. Option B, $426.37, is incorrect as it is a slightly higher amount due to rounding off. Option C, $363.20, and option D, $526.38, are incorrect because they are not the result of calculating 54% of $789.56 accurately.

Question 5 of 5

What is the result of dividing 3.44 by 0.6?

Correct Answer: B

Rationale: To divide 3.44 by 0.6, we perform the division as follows: 3.44 / 0.6 = 5.73 The correct answer is B. When dividing a decimal number by another decimal number, we move the decimal point in both numbers to make the divisor a whole number. Then we divide as usual. Choices A, C, and D are incorrect as they do not result from the correct division.
