HESI A2 Practice Test Math Questions

Question 1 of 5

What is the result of adding 1/2 + 4/5?

Correct Answer: A

Rationale: To add 1/2 + 4/5, we need a common denominator, which is 10 in this case. 1/2 becomes 5/10 and 4/5 remains as 4/5. Adding them gives 9/10. Converting 9/10 to a mixed number, we get 1 3/10, which is choice A. Choices B, C, and D are incorrect as they do not correctly represent the sum of the fractions.

Question 2 of 5

Solve for x: 3(x - 4) = 18.

Correct Answer: A

Rationale: To solve for x in the equation 3(x - 4) = 18, first distribute the 3: 3x - 12 = 18. Next, add 12 to both sides to isolate the variable: 3x = 30. Finally, divide by 3 to find x = 10. Choice A is correct because it correctly solves the equation step by step. Choices B, C, and D are incorrect as they do not follow the correct mathematical operations to solve for x.

Question 3 of 5

An office manager makes photocopies for the entire staff each day. At the end of the week, she finds that the photocopy machine has made a total of 3,475 copies. If 6 people used the copier and each person made the same number of copies, how many copies did each person make?

Correct Answer: A

Rationale: The correct answer is A: 579 copies. To find the number of copies each person made, divide the total number of copies (3,475) by the number of people who used the copier (6). 3,475 ÷ 6 = 579. Each person made 579 copies. Summary: - Choice B (680 copies) is incorrect because it does not evenly divide into the total number of copies. - Choice C (670 copies) is incorrect because it is not an even division of the total number of copies. - Choice D (585 copies) is incorrect because it is not the result of dividing the total number of copies by the number of people who used the copier.

Question 4 of 5

Which of these percentages equals 1.25?

Correct Answer: D

Rationale: To find which percentage equals 1.25, we convert 1.25 to a percentage by multiplying it by 100. 1.25 * 100 = 125%. Therefore, the correct choice is D. Choice A (1250%) is incorrect as it represents 12.5, not 1.25. Choices B (25%) and C (50%) are also incorrect as they are significantly lower than 1.25.

Question 5 of 5

In a class of 25 students, 44% are boys. How many boys are there?

Correct Answer: B

Rationale: To find the number of boys, we first calculate 44% of 25 (total students). This gives us 0.44 * 25 = 11 boys. Therefore, the correct answer is B. Choice A (10 boys) is incorrect as it is based on rounding down from 44%, and choices C (9 boys) and D (13 boys) are incorrect as they do not match the calculated 11 boys.
