HESI A2 Practice Test Math Questions

Question 1 of 5

Erin has 6.25 peach pies. She gives Rose 3.75 of the peach pies. How many pies does Erin have left?

Correct Answer: A

Rationale: First, determine how many peach pies Erin has left after giving 3.75 to Rose: 6.25 - 3.75 = 2.5 peach pies. Since she can't have half a pie, it rounds down to 2. So, Erin has 2 peach pies left, making option A the correct answer. Option B, C, and D are incorrect as they do not reflect the accurate calculation of the remaining pies.

Question 2 of 5

How many liters are in 300 milliliters?

Correct Answer: C

Rationale: To convert milliliters to liters, you divide by 1000 because there are 1000 milliliters in a liter. So, 300 milliliters divided by 1000 equals 0.3 liters. A: 0.03 liters - Incorrect, the decimal point is misplaced. B: 3 liters - Incorrect, this is 1000 milliliters, not 300. D: 0.003 liters - Incorrect, the decimal point is misplaced.

Question 4 of 5

A label states 1 mil contains 500 mg. How many mils are there if there are 1.5 grams?

Correct Answer: C

Rationale: To calculate the number of mils in 1.5 grams, we first convert 1.5 grams to milligrams: 1.5g * 1000mg/g = 1500mg. Then, we divide 1500mg by the amount in 1 mil (500mg/mil) to get 3 mils. Choice C is correct. Choices A, B, and D are incorrect because they do not follow the correct conversion process. Choice A (9 mils) results from dividing 1500mg by 500mg, which is incorrect. Choice B (2 mils) and Choice D (5 mils) also do not yield the correct answer when dividing 1500mg by 500mg.

Question 5 of 5

What is the result of subtracting 7 7/10 from 3 4/5?

Correct Answer: A

Rationale: To subtract mixed numbers, convert them to improper fractions. 3 4/5 = 19/5 and 7 7/10 = 77/10. Subtracting gives 19/5 - 77/10 = 38/10 - 77/10 = -39/10. Convert back to a mixed number: -39/10 = -3 9/10 (choice A). Other choices are incorrect as they do not match the correct result.
