HESI A2 Quizlet Math Questions
Question 1 of 5
What is the result of adding 7 2/3 and 5 5/12?
Correct Answer: C
Rationale: To add 7 2/3 and 5 5/12, first convert both mixed numbers to improper fractions: 7 2/3 = 23/3 and 5 5/12 = 65/12. Then, add the fractions: 23/3 + 65/12 = 92/12 + 65/12 = 157/12. Finally, convert 157/12 back to a mixed number: 157 ÷ 12 = 13 with a remainder of 1, resulting in 13 1/12. Therefore, the correct answer is C (13 1/12). Choices A, B, and D are incorrect as they do not match the calculated sum of the two mixed numbers.
Question 2 of 5
How many meters are in 5 kilometers?
Correct Answer: B
Rationale: The correct answer is B: 5000. To convert kilometers to meters, you need to multiply by 1000 since there are 1000 meters in a kilometer. So, 5 kilometers x 1000 = 5000 meters. Choice A (1000) is the number of meters in 1 kilometer, not 5. Choice C (10000) is the result of multiplying 10 kilometers by 1000. Choice D (500) is incorrect as it is not the correct conversion from kilometers to meters.
Question 3 of 5
In a survey, 120 people were asked if they could swim. If 85% said they could, how many people could swim?
Correct Answer: B
Rationale: To find the number of people who can swim, multiply the total number of people surveyed by the percentage that can swim. In this case, 120 x 0.85 = 102. Choice B is correct. Choice A is too low as it doesn't account for the 85%. Choice C is too high. Choice D is also too low.
Question 4 of 5
If a parent changes their baby 6 times a day, how many diapers will be needed in a year?
Correct Answer: A
Rationale: To calculate the number of diapers needed in a year, we multiply the number of times the baby is changed per day (6) by the number of days in a year (365). So, 6 diapers/day x 365 days/year = 2190 diapers (Choice A). This is the correct answer as it accounts for daily changes throughout the year. Choices B, C, and D are incorrect because they do not accurately calculate the total number of diapers needed based on the given information.
Question 5 of 5
How many meters are in 3 kilometers?
Correct Answer: A
Rationale: To convert kilometers to meters, we need to multiply by 1000 since there are 1000 meters in 1 kilometer. Therefore, 3 kilometers x 1000 = 3000 meters. This is why choice A (3000 meters) is correct. Choices B, C, and D are incorrect because they do not follow the conversion factor of 1000 meters in 1 kilometer. Choice B (2000 meters) is too low, choice C (3500 meters) is too high, and choice D (2500 meters) is also too low.
