HESI A2 Math Practice Questions
Question 1 of 5
What is 60% of 150?
Correct Answer: B
Rationale: To find 60% of 150, you multiply 150 by 0.6 (which represents 60%). 150 * 0.6 = 90 Therefore, the correct answer is B: 90. Choice A is incorrect as 80 is not the result of multiplying 150 by 0.6. Choice C is incorrect as 120 is not 60% of 150. Choice D is incorrect as it is the same as choice A.
Question 2 of 5
Subtract 5/6 - 3/4.
Correct Answer: A
Rationale: To subtract fractions, we need a common denominator. In this case, the least common multiple of 6 and 4 is 12. So, 5/6 becomes 10/12 and 3/4 becomes 9/12. Subtracting, 10/12 - 9/12 = 1/12, which is the correct answer (A). The other choices are incorrect because they do not result from the proper subtraction of the fractions using a common denominator. Choice B simplifies to 1/12 but is not the correct calculation. Choice C (1/2) and Choice D (1/8) are unrelated to the subtraction of the given fractions.
Question 3 of 5
Subtract 28 3/4 - 5 5/6.
Correct Answer: A
Rationale: To subtract mixed numbers, first convert them to improper fractions. 28 3/4 = 115/4 and 5 5/6 = 35/6. Then subtract: 115/4 - 35/6. Find a common denominator, which is 12. So, 115/4 becomes 345/12 and 35/6 becomes 70/12. Subtract to get 275/12 = 22 & 11/12, which is choice A. The other choices are incorrect because they do not match the correct result obtained through the step-by-step subtraction of the mixed numbers converted to improper fractions.
Question 4 of 5
A die is rolled. What is the probability of getting 5?
Correct Answer: A
Rationale: The correct answer is A: 16.67%. There is only one face of the die with a 5, out of a total of 6 faces. Therefore, the probability of rolling a 5 is 1/6, which is approximately 16.67%. Other choices are incorrect: B: 20% - This is the probability if there were 5 faces with a 5. C: 50% - This would be the probability if there were only two faces on the die. D: 83.33% - This would be the probability if there were 5 faces with a 5.
Question 5 of 5
What is the probability of rolling an odd number on a six-sided die?
Correct Answer: A
Rationale: The correct answer is A (50%). There are 3 odd numbers (1, 3, 5) on a six-sided die out of a total of 6 possible outcomes (1, 2, 3, 4, 5, 6). To calculate the probability, you divide the number of favorable outcomes (3) by the total number of outcomes (6), which equals 0.5 or 50%. Choice B (66.70%) is incorrect because it assumes there are 4 odd numbers out of 6, which is not the case. Choice C (33.30%) is incorrect because it calculates the probability of rolling an even number. Choice D (25%) is incorrect as it represents the probability of rolling a specific number (1) out of 6 possible outcomes.
