HESI A2 Math Practice Test 2022 Questions
Question 1 of 5
A medication dosage is listed as 1/4 gram. What is the equivalent dosage in milligrams (1 gram = 1000 milligrams)?
Correct Answer: B
Rationale: 1/4 gram is equivalent to 1/4 * 1000 milligrams (since 1 gram = 1000 milligrams).
1/4 * 1000 = 250 milligrams.
Therefore, the equivalent dosage in milligrams is 250mg, which corresponds to option B. The other choices are incorrect because they do not correctly convert 1/4 gram to milligrams using the conversion factor of 1 gram = 1000 milligrams.
Question 2 of 5
A group of 8 friends went out to eat at a restaurant. They decided to split the bill evenly. If the bill totaled $120, how much did each friend pay?
Correct Answer: A
Rationale:
To determine how much each friend paid, divide the total bill amount by the number of friends. In this scenario, $120 · 8 friends = $15.
Therefore, each friend paid $15.
Choice B ($10) is incorrect because dividing $120 by 8 does not yield $10.
Choice C ($12) is incorrect because dividing $120 by 8 does not yield $12.
Choice D ($20) is incorrect because dividing $120 by 8 does not yield $20.
Question 3 of 5
Sally was able to eat 5/8 of her lunch. John ate 75% of his lunch. Who ate more of their meal?
Correct Answer: B
Rationale:
To compare who ate more of their meal, we need to convert the fractions to the same format. John ate 75% of his lunch, which is equivalent to 3/4. Sally ate 5/8 of her lunch. Comparing 3/4 to 5/8, we find that 3/4 is greater than 5/8.
Therefore, John ate more of his meal than Sally.
Choice B, John, is the correct answer.
Choices A, C, and D are incorrect because John consumed 3/4 of his lunch, which is more than 5/8 that Sally consumed, making him the one who ate more of his meal.
Question 4 of 5
What is 33% of 300?
Correct Answer: D
Rationale:
To find 33% of 300, you multiply 300 by 0.33 (which is the decimal equivalent of 33%). 300 * 0.33 = 99.
Therefore, 33% of 300 equals 99.
Choice A (3) is incorrect as it is too small for 33% of 300.
Choice B (9) is incorrect as it does not reflect the correct calculation for finding 33% of 300.
Choice C (33) is incorrect as it represents the percentage value itself, not the result of calculating 33% of 300.
Question 5 of 5
What is the value of x in the ratio and proportion 0.1:10=x:400?
Correct Answer: B
Rationale:
To solve the proportion 0.1:10=x:400, first, simplify the left side to 1:100.
Then, set up the proportion as 1:100=x:400. Cross multiply to get x = 4.
Therefore, the correct answer is B.
Choice A (5) is incorrect because it does not match the calculated value of x.
Choice C (50) is incorrect as it is not the result of solving the proportion provided.
Choice D (25) is incorrect as it does not align with the correct calculation of x.
