HESI A2 Math Practice Questions
Question 1 of 5
Solve for x: 3x + 9 = 0.
Correct Answer: B
Rationale: To solve for x in the equation 3x + 9 = 0, first, subtract 9 from both sides to isolate 3x. This gives you 3x = -9. Next, divide both sides by 3 to solve for x, which results in x = -3. Therefore, the correct answer is B. Choice A is incorrect as it does not account for the correct arithmetic operations. Choice C is incorrect because it does not yield a solution that satisfies the equation. Choice D is incorrect as it does not follow the correct steps to solve for x.
Question 2 of 5
Subtract 2 5\8 - 7\8 and reduce.
Correct Answer: A
Rationale: To subtract 2 5\8 - 7\8, first convert both mixed numbers to improper fractions: 2 5\8 = 21\8 and 7\8 = 7\8. Then, subtract the fractions: 21\8 - 7\8 = 14\8 = 1 & 6\8. Finally, simplify the mixed number to 1 & 5\8. Choice A is correct because after subtracting, the result simplifies to 1 & 5\8. Choices B, C, and D are incorrect as they do not represent the correct result of the subtraction calculation.
Question 3 of 5
If the quotient is 4 and the dividend is 12, what is the divisor?
Correct Answer: C
Rationale: To find the divisor, we use the formula Dividend = Divisor x Quotient. Given Dividend = 12 and Quotient = 4, we substitute these values into the formula: 12 = Divisor x 4. Solving for Divisor, we get Divisor = 12 / 4 = 3. Therefore, the correct answer is C (4). Choice A (3) is incorrect because 12 divided by 3 is 4, not the given quotient of 4. Choice B (6) is incorrect because 12 divided by 6 is 2, not the given quotient of 4. Choice D (9) is incorrect because 12 divided by 9 is 1.33, not the given quotient of 4.
Question 4 of 5
A worker in a warehouse ships 9 boxes each day. If every box must contain 3 shipping labels, how many shipping labels does the worker need each day?
Correct Answer: B
Rationale: To find the total number of shipping labels needed per day, we multiply the number of boxes by the number of labels per box: 9 boxes x 3 labels = 27 labels. This is why choice B (27 labels) is correct. Choice A (24 labels) results from multiplying the boxes by labels incorrectly. Choice C (20 labels) and choice D (30 labels) are both too low and too high respectively, indicating an incorrect understanding of the calculation required.
Question 5 of 5
How many milliliters are in 4 liters?
Correct Answer: C
Rationale: To convert liters to milliliters, you need to multiply by 1000 since there are 1000 milliliters in 1 liter. So, 4 liters x 1000 = 4000 milliliters. Therefore, the correct answer is C. Choice A and B are incorrect as they are too small. Choice D is incorrect as it represents the original amount in liters, not the converted amount in milliliters.
