TEAS Math Questions Questions
Question 1 of 5
What percentage of the staff is certified and available to work in the neonatal unit during the holiday if 35% are on vacation and 20% of the remainder are certified?
Correct Answer: A
Rationale: To find the percentage of staff certified and available during the holiday, we first calculate the remaining staff after 35% are on vacation (100% - 35% = 65%). Then, 20% of the remaining 65% are certified (20% of 65% = 0.20 * 65% = 13%). Therefore, the percentage of staff certified and available is 13% (0.13), which corresponds to choice B. However, the question asks for the percentage, not the decimal representation. To convert 0.13 to a percentage, we multiply by 100, resulting in 13%. Therefore, the correct answer is A (0.13 expressed as a percentage is 13%). Choices C and D are incorrect as they do not match the calculated percentage.
Question 2 of 5
A container holds 10 liters of water. If 25% of the water is used, how many liters are left?
Correct Answer: A
Rationale: To calculate how many liters are left after using 25%, we first find 25% of 10 liters: 10 * 0.25 = 2.5 liters used. Subtracting this from the initial amount gives us the remaining water: 10 - 2.5 = 7.5 liters left. Therefore, choice A (7.5 liters) is correct. Choice B (8 liters) is incorrect because it doesn't account for the water that was used. Choice C (6.5 liters) and choice D (8.5 liters) are also incorrect as they do not reflect the correct calculation based on the given information.
Question 3 of 5
A student scores 85% on a test with 50 questions. How many questions did the student answer correctly?
Correct Answer: C
Rationale: To find how many questions the student answered correctly: 1. Calculate 85% of 50: 0.85 * 50 = 42.5 2. Since the student can't answer half a question, round down to the nearest whole number: 42 Therefore, the student answered 42 questions correctly. Option C is correct. Incorrect options: A: 40 questions - Too low, as the student scored above 40. B: 42 questions - Close but not rounded correctly. D: 45 questions - Too high, as the student's score was 85%.
Question 4 of 5
In a city with a population of 51,623, 9.5% of the population voted for a new proposition. How many people approximately voted?
Correct Answer: B
Rationale: To calculate the number of people who voted, we multiply the population by the percentage who voted: 51,623 * 0.095 = 4,904.785. Since we can't have a fraction of a person, we round to the nearest whole number, which is 5,000. Explanation: A: 3,000 is too low as it doesn't account for the entire 9.5%. B: Correct. 5,000 is the closest estimate after rounding. C: 7,000 is too high as it overestimates the number of voters. D: 10,000 is too high and doesn't align with the calculated value.
