HESI A2 Practice Test Math Questions
Question 1 of 5
What is (12/15) · (3/5) = ?
Correct Answer: A
Rationale:
To divide fractions, you multiply by the reciprocal of the divisor. (12/15) · (3/5) is the same as (12/15) * (5/3). Cancel out common factors to simplify: 12 · 3 = 4, 15 · 5 = 3. So, the expression simplifies to 4/3, which is 1 1/3 in mixed number form.
Choice A, 1 1/3, is the correct answer.
Choices B, C, and D are incorrect because they do not represent the simplified form of the division of the given fractions.
Question 2 of 5
A medication order is written as 3/4 of a tablet. If each tablet is 500mg, what is the equivalent dosage in milligrams?
Correct Answer: B
Rationale:
Rationale:
- Each tablet is 500mg.
- The medication order is for 3/4 of a tablet.
-
To find the equivalent dosage in milligrams, we need to calculate 3/4 of 500mg.
- 3/4 of 500mg = (3/4) * 500mg = 0.75 * 500mg = 375mg.
-
Therefore, the equivalent dosage in milligrams is 375mg.
Question 3 of 5
7:5=91:x. Find x.
Correct Answer: A
Rationale:
To solve the proportion 7:5=91:x, cross multiply to get 7x = 5 * 91.
Then, solve for x by dividing both sides by 7, which gives x = 65.
Therefore, the correct answer is x=65.
Choice B, x=55, is incorrect because it does not satisfy the proportion equation.
Choices C and D, x=75 and x=85, are also incorrect as they do not match the calculated value of x when the proportion is solved.
Question 4 of 5
A woman received a bottle of perfume as a present. The bottle contains 1/2 oz of perfume. How many milliliters is this?
Correct Answer: A
Rationale: 1/2 oz of perfume is equal to approximately 15 mL.
To convert ounces to milliliters, we need to know that 1 oz is approximately 30 mL.
Therefore, half an ounce, which is 1/2 oz, would be half of 30 mL, which equals 15 mL.
Choice B, 20 mL, is incorrect as it does not correspond to the conversion factor of 1 oz to 30 mL.
Choice C, 10 mL, is incorrect as it is half of the actual value.
Choice D, 50 mL, is incorrect as it is the value of 1 oz rather than half an ounce.
Question 5 of 5
Convert the decimal 0.98 to a percent.
Correct Answer: A
Rationale:
To convert a decimal to a percent, you multiply the decimal by 100. In this case, 0.98 100 = 98%.
Therefore, the correct answer is A, which is 98%.
Choice B (9%) is incorrect as it results from an error in calculation.
Choice C (98) is incorrect as it lacks the percent symbol.
Choice D (99%) is incorrect as it is not the equivalent percentage of 0.98.
