HESI A2 Practice Test Math Questions
Question 1 of 5
Erin has 6.25 peach pies. She gives Rose 3.75 of the peach pies. How many pies does Erin have left?
Correct Answer: A
Rationale: First, determine how many peach pies Erin has left after giving 3.75 to Rose: 6.25 - 3.75 = 2.5 peach pies. Since she can't have half a pie, it rounds down to 2. So, Erin has 2 peach pies left, making option A the correct answer. Option B, C, and D are incorrect as they do not reflect the accurate calculation of the remaining pies.
Question 2 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 3 of 5
Which of the following is equivalent to 0.0009?
Correct Answer: C
Rationale: The correct answer is C: 0.09%. To convert 0.0009 to a percentage, you move the decimal point two places to the right, resulting in 0.09%. Option A (0.009%) is incorrect as it would be the equivalent of 0.00009. Option B (0.9%) is incorrect as it represents 0.009. Option D (9%) is incorrect as it is equivalent to 0.09, which is 100 times greater than the given value.
Question 4 of 5
X/4 = 9/x, solve for x.
Correct Answer: A
Rationale: To solve for x in the equation X/4 = 9/x, we can cross multiply to get X * x = 4 * 9. Simplifying further, we get x^2 = 36, so x = √36 = 6. Choice A (x = 6) is correct. Choices B, C, and D are incorrect because they do not satisfy the equation when substituted back in. B: 6/4 ≠ 9/6, C: 6/4 ≠ 9/9, D: 6/4 ≠ 9/2.
Question 5 of 5
Change 1/6 to a percent.
Correct Answer: A
Rationale: To change 1/6 to a percent, first divide 1 by 6 to get 0.1667. Then, multiply by 100 to convert it to a percentage, which equals 16.67%. Choice A is correct because it accurately represents the conversion. Choices B, C, and D are incorrect as they do not reflect the accurate calculation for converting 1/6 to a percentage.
