Math HESI A2 Practice Test Questions

Question 1 of 5

How many milligrams are in 7 grams?

Correct Answer: A

Rationale: To convert grams to milligrams, you multiply by 1000 since there are 1000 milligrams in a gram. So, 7 grams x 1000 = 7000 mg. Therefore, the correct answer is A: 7000 mg. Option B (7 mg) is incorrect because it represents the original unit (grams). Option C (700 mg) is incorrect as it is a partial conversion error. Option D (70 mg) is incorrect as it is a multiple of 10 error.

Question 2 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 3 of 5

If Kevin can wash 30 cars in 15 minutes, how many minutes will it take him to wash 100 cars?

Correct Answer: A

Rationale: To find the time to wash 100 cars, we can set up a proportion: 30 cars / 15 minutes = 100 cars / x minutes. Cross multiply to get 30x = 1500, then divide by 30 to find x = 50 minutes. Therefore, the correct answer is A. Choice B, 55 minutes, is incorrect as it does not align with the calculation. Choice C, 30 minutes, is incorrect as it is the time to wash 60 cars, not 100. Choice D, 45 minutes, is incorrect as it does not match the calculated time of 50 minutes for washing 100 cars.

Question 4 of 5

What is the result of dividing 3.44 by 0.6?

Correct Answer: B

Rationale: To divide 3.44 by 0.6, we perform the division as follows: 3.44 / 0.6 = 5.73 The correct answer is B. When dividing a decimal number by another decimal number, we move the decimal point in both numbers to make the divisor a whole number. Then we divide as usual. Choices A, C, and D are incorrect as they do not result from the correct division.

Question 5 of 5

How many ounces are in 3 quarts?

Correct Answer: D

Rationale: To convert quarts to ounces, we know that 1 quart equals 32 ounces. Therefore, 3 quarts would equal 3 x 32 = 96 ounces. This makes answer choice D (96 ounces) the correct option. Choice A (64 ounces) is incorrect because it miscalculates the conversion. Choice B (32 ounces) is incorrect as it represents 1 quart, not 3 quarts. Choice C (48 ounces) is also incorrect as it is an intermediate value between the correct answer and the incorrect answer A.
