HESI A2 Math Practice Test 2023 Questions

Question 1 of 5

Which of the following fractions is the largest? 3/8, 3/9, 3/6, 3/7

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.

Question 2 of 5

What is 80% of 55?

Correct Answer: B

Rationale: To find 80% of 55, you multiply 55 by 0.8 (which is the decimal equivalent of 80%). So, 55 * 0.8 = 44. Therefore, the correct answer is B (44). Choice A (40) is incorrect as it represents 80% of 50, not 55. Choices C (39) and D (45) are also incorrect calculations.

Question 3 of 5

How many milligrams are in 3.4 grams?

Correct Answer: B

Rationale: To convert grams to milligrams, you multiply by 1000 since there are 1000 milligrams in 1 gram. Therefore, 3.4 grams x 1000 = 3400 mg. Choice B is correct because it correctly converts grams to milligrams. Choices A, C, and D are incorrect as they do not correctly apply the conversion factor from grams to milligrams. Option A is off by a factor of 10, option C is off by a factor of 100, and option D is off by a factor of 10.

Question 4 of 5

The metric system of measurement was developed in France during Napoleon's reign. It is based on what multiplication factor?

Correct Answer: C

Rationale: The correct answer is C: 10. The metric system is based on multiples of 10, making conversions between units easy and logical. This factor allows for a systematic and uniform system of measurement, which is essential for scientific accuracy and global standardization. Choices A, B, and D are incorrect because the metric system is not based on the length of Napoleon's forearm, the number 2, or the atomic weight of helium. These options do not align with the foundational principles of the metric system, which is built on the decimal system for simplicity and consistency.

Question 5 of 5

Subtract 12 1/8 - 9 1/2.

Correct Answer: A

Rationale: To subtract mixed numbers, first convert them to improper fractions. 12 1/8 = 97/8 and 9 1/2 = 19/2. Then, subtract the fractions: 97/8 - 19/2 = 97/8 - 38/8 = 59/8. Finally, convert the result back to a mixed number: 59/8 = 7 3/8. Therefore, the correct answer is A: 2 5/8. Choices B, C, and D are incorrect because they do not match the result of the subtraction calculation.
