HESI A2 Math Practice Test Questions
Question 1 of 5
Subtract and simplify: 8� − 1�.
Correct Answer: A
Rationale: To subtract mixed numbers, convert them to improper fractions. 8� = 33/4 and 1� = 3/2. Subtracting, we get 33/4 - 3/2 = 33/4 - 6/4 = 27/4 = 6�, which simplifies to 4�. Therefore, the correct answer is 4�. Choice B is incorrect as it represents the intermediate step of 6� before simplification. Choice C is incorrect as it is the result of the subtraction but not simplified. Choice D is incorrect as it is the original mixed number 7�, not the simplified result.
Question 2 of 5
If the total cost of his purchase was $9.38 and he gave the cashier $20, how much change did he receive?
Correct Answer: D
Rationale: To determine the amount of change received, you need to subtract the total cost from the amount given. $20 - $9.38 = $10.62. Therefore, he received $10.62 in change. Option A ($0.62) is incorrect as it is the difference in cents, not dollars. Option B ($5.02) is incorrect as it does not reflect the correct subtraction. Option C ($9.38) is incorrect as it represents the total cost of the purchase, not the change received.
Question 3 of 5
Positive integers are numbers greater than zero. Which of the following expressions results in the largest positive number?
Correct Answer: C
Rationale: To find the largest positive number among the expressions, we evaluate each one: A) (2 + 3)^2 = 5^2 = 25 B) 5 x 7 + 2 = 35 + 2 = 37 C) 10^2 - 4^2 = 100 - 16 = 84 D) (8 - 1) x 3 = 7 x 3 = 21 Therefore, the expression that results in the largest positive number is 10^2 - 4^2, which equals 84. Choices A, B, and D result in smaller numbers.
Question 4 of 5
What is the result of dividing 2,032 by 25?
Correct Answer: C
Rationale: When dividing 2,032 by 25, you find that 25 goes into 2,032 a total of 81 times without exceeding it. The remainder is 7, not 28 as stated in choice B. This is because 25 * 81 = 2,025, leaving a difference of 7, not 28. Choice A and D are incorrect because they do not correctly represent the division result of 2,032 by 25.
Question 5 of 5
What is the result of adding 12 + 2 + 312?
Correct Answer: C
Rationale: To find the sum of 12 + 2 + 312, you simply need to add these numbers together. 12 + 2 = 14, and when you add 312 to 14, you get the correct total of 326. Therefore, the correct answer is C. Choice A (936), choice B (374.4), and choice D (318.24) are incorrect as they do not represent the correct sum of the given numbers.
