Math HESI A2 Practice Test Questions

Question 1 of 5

How many milliliters are in 3 liters?

Correct Answer: B

Rationale: To convert liters to milliliters, you need to know that 1 liter is equal to 1000 milliliters. Therefore, to find how many milliliters are in 3 liters, you would multiply 3 by 1000, which equals 3000 milliliters. So, the correct answer is B: 3000 milliliters. A is incorrect because it is the result of multiplying 3 by 100, not 1000. C is incorrect because it is half of 3000, not the actual conversion. D is incorrect as it is one-tenth of the correct answer.

Question 2 of 5

Solve for x: x/5 = 3/10.

Correct Answer: D

Rationale: To solve x/5 = 3/10, first cross multiply to get 10x = 15. Then divide both sides by 10 to isolate x, giving x = 1.5. This is the correct answer as it satisfies the original equation. Choices A, B, and C are incorrect as they do not match the result obtained from solving the equation step by step.

Question 3 of 5

What is 54% of $789.56?

Correct Answer: A

Rationale: To calculate 54% of $789.56, you multiply 789.56 by 0.54. This gives you $426.36, which is option A. The correct answer is A because multiplying the percentage (54%) by the total amount ($789.56) gives the accurate result. Option B, $426.37, is incorrect as it is a slightly higher amount due to rounding off. Option C, $363.20, and option D, $526.38, are incorrect because they are not the result of calculating 54% of $789.56 accurately.

Question 4 of 5

A patient's temperature is measured as 38.5 degrees Celsius. What is their temperature in Fahrenheit?

Correct Answer: D

Rationale: To convert Celsius to Fahrenheit, you use the formula: Fahrenheit = (Celsius x 1.8) + 32. Given the patient's temperature is 38.5 degrees Celsius, Fahrenheit = (38.5 x 1.8) + 32 = 104.9 degrees Fahrenheit (Option D). Options A, B, and C are incorrect as they do not match the correct conversion using the formula.

Question 5 of 5

Add: 3 1/8 + 1 1/4.

Correct Answer: A

Rationale: To add 3 1/8 and 1 1/4, first convert both to improper fractions: 3 1/8 = 25/8 and 1 1/4 = 5/4. Then, add the fractions: 25/8 + 5/4 = 50/8 + 10/8 = 60/8 = 7 1/2. Convert 7 1/2 back to a mixed number: 7 1/2 = 6 2/8 = 6 1/4 = 4 3/8, which is the correct answer (A). Choice B (4 1/2) is incorrect as it doesn't match the calculated sum. Choice C (4 3/4) is incorrect as it is not the simplified form of the sum. Choice D (5 1/4) is incorrect as it is higher than the calculated sum.
