HESI A2 Math Practice Questions

Question 1 of 5

What is 60% of 150?

Correct Answer: B

Rationale: To find 60% of 150, you multiply 150 by 0.6 (which represents 60%). 150 * 0.6 = 90 Therefore, the correct answer is B: 90. Choice A is incorrect as 80 is not the result of multiplying 150 by 0.6. Choice C is incorrect as 120 is not 60% of 150. Choice D is incorrect as it is the same as choice A.

Question 2 of 5

What is the temperature in Celsius when it is 98.6 degrees Fahrenheit?

Correct Answer: B

Rationale: To convert Fahrenheit to Celsius, we use the formula: C = (F - 32) / 1.8. Plugging in 98.6 for F gives C = (98.6 - 32) / 1.8 = 37. Therefore, the correct answer is B: 37 Celsius. Choice A (35 Celsius) is incorrect as it is too low. Choice C (38 Celsius) is incorrect as it is too high. Choice D (36.5 Celsius) is incorrect as it does not match the calculated conversion.

Question 3 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 4 of 5

Solve for x: x + 44 / 2x = 11.

Correct Answer: A

Rationale: To solve for x in the equation x + 44 / 2x = 11, we first simplify by multiplying both sides by 2x to get rid of the fraction. This gives us x^2 + 44 = 22x. Rearranging, we get x^2 - 22x + 44 = 0. This quadratic equation can be factored as (x - 11)(x - 4) = 0. Therefore, x = 11 or x = 4. However, x = 4 does not satisfy the original equation, so the correct answer is x = 11 (Choice A). Choices B, C, and D are incorrect as they do not satisfy the equation after substitution.

Question 5 of 5

Subtract 6 1/2 - 2 2/3.

Correct Answer: A

Rationale: To subtract mixed numbers, convert them to improper fractions: 6 1/2 = 13/2 and 2 2/3 = 8/3. Next, find a common denominator, which is 6. Subtract the fractions: 13/2 - 8/3 = 39/6 - 16/6 = 23/6. Convert the result back to a mixed number: 23/6 = 3 5/6, which is the correct answer (C). The other choices are incorrect because they do not match the result of the subtraction calculation.
