HESI A2 Math Practice Test 2024 Questions
Question 1 of 5
What is the result of adding 7/21 + 10/21?
Correct Answer: A
Rationale: To add fractions, ensure the denominators are the same. Here, both fractions already have a common denominator of 21. Add the numerators: 7 + 10 = 17. So, the result is 17/21 (choice A). Other choices are incorrect because: B: 15/21 - Incorrect, the sum of the numerators is 17, not 15. C: 9/21 - Incorrect, the sum of the numerators is 17, not 9. D: 10/21 - Incorrect, this is just one of the fractions being added, not the result of the addition.
Question 2 of 5
Ratio and proportion: 6:10=24:x
Correct Answer: A
Rationale: To find x in the proportion 6:10=24:x, we first calculate the ratio of the given numbers, 6/10=24/x. Simplifying, we get 0.6=24/x. Cross multiplying, we get x=24/0.6=40. Therefore, the correct answer is A. Choice B is incorrect as it does not satisfy the proportion. Choice C is incorrect as it is too large compared to the correct answer. Choice D is incorrect as it is too small compared to the correct answer.
Question 3 of 5
A kite has a top base of 20cm, a bottom base of 30cm, and two equal side lengths of 15cm. What is its perimeter?
Correct Answer: C
Rationale: To find the perimeter of the kite, we add up all the sides. Top base = 20cm Bottom base = 30cm Two equal side lengths = 15cm each Perimeter = 20 + 30 + 15 + 15 = 80cm Therefore, the correct answer is C (70cm). Choice A (55cm) is incorrect as it does not consider all the sides of the kite. Choice B (65cm) is incorrect as it does not account for the top and bottom bases. Choice D (80cm) is incorrect as it miscalculates the perimeter by not adding the side lengths correctly.
Question 4 of 5
Convert 2100 to standard time.
Correct Answer: C
Rationale: The correct answer is C: 9:00 PM. To convert 2100 to standard time, subtract 12 hours from 2100 since military time is based on a 24-hour clock. 2100 - 1200 = 900, which translates to 9:00 PM. Choice A (12:00 PM) is incorrect as it would be noon, not evening. Choice B (2:00 AM) is incorrect as it represents the early morning. Choice D (2:00 PM) is incorrect as it is in the afternoon, not evening.
Question 5 of 5
If a student earns $120 for a 10-hour tutoring session and works 6 hours, how much did the student earn?
Correct Answer: A
Rationale: To find how much the student earned for working 6 hours, we can use the formula: Earnings = (Total pay / Total hours) x Hours worked. In this case, Earnings = ($120 / 10 hours) x 6 hours = $72. Therefore, the correct answer is A: $72. Choice B, $90, is incorrect as it does not match the calculated amount. Choice C, $80, is also incorrect. Choice D, $50, is incorrect because it is too low based on the calculated earnings for 6 hours.
