HESI A2 Math Practice Test 2024 Questions
Question 1 of 5
A man is reading. He reads two chapters a day. How long will it take if there are 6 pages per chapter and 798 pages total?
Correct Answer: A
Rationale: To find the number of days it will take the man to read 798 pages, first calculate the total number of chapters: 798 pages / (6 pages/chapter) = 133 chapters. Since he reads 2 chapters a day, divide the total chapters by 2 to get 133 chapters / 2 chapters/day = 66.5 days. Therefore, the correct answer is A: 66 & 1/2. Incorrect Choices: B: 399 - Incorrect as it does not reflect the correct calculation. C: 75 & 1/2 - Incorrect, the calculation is incorrect. D: 133 - Incorrect, this represents the total number of chapters, not the number of days.
Question 2 of 5
25 1/7 - 12 5/7 = ?
Correct Answer: A
Rationale: To subtract mixed numbers, start by subtracting the whole numbers (25 - 12 = 13). Then subtract the fractions separately (1/7 - 5/7 = -4/7). Combine the whole number and fraction results to get 13 - 4/7 = 12 3/7, which is choice A. Other choices are incorrect as they do not match the correct result after the subtraction process. Choice B doesn't account for the fraction subtraction correctly. Choice C is not the correct result of the subtraction. Choice D is the result of only subtracting the whole numbers, ignoring the fractions.
Question 3 of 5
Change the following fraction into a ratio: 19/40
Correct Answer: A
Rationale: The correct answer is A: 19:40. To convert a fraction to a ratio, we simply write the numerator followed by a colon and then the denominator. In this case, 19/40 converts to 19:40. The other choices are incorrect because B switches the positions of the numbers, C simplifies the fraction incorrectly, and D simplifies the fraction to a different ratio. Therefore, the correct answer is A as it accurately represents the ratio of 19 to 40.
Question 4 of 5
A set of temperature readings has a range of 5 degrees Celsius. What does this tell you about the data?
Correct Answer: C
Rationale: The correct answer is C because the range of 5 degrees Celsius indicates the difference between the highest and lowest temperatures in the set is 5 degrees. This is the definition of range in statistics. A is incorrect because the range does not provide information about the average temperature. B is incorrect because the range only tells us the spread between the highest and lowest temperatures, not that all temperatures are within 5 degrees of each other. D is incorrect because the range does not indicate how many temperatures are in the set, just the difference between the highest and lowest temperatures.
Question 5 of 5
Bill has 2.5 vacation days left for the rest of the year and 1.25 sick days left. If Bill uses all of his sick days and his vacation days, how many days will he have off work?
Correct Answer: D
Rationale: To calculate the total days off, add Bill's remaining vacation days (2.5) and sick days (1.25): 2.5 + 1.25 = 3.75 days. Since Bill is using all his sick days and vacation days, he will have 3 full days off work. Therefore, the correct answer is D (4 days). Choices A, B, and C are incorrect as they do not consider the combination of remaining days and assume a different outcome.
