TEAS Math Questions Questions
Question 1 of 5
If a person spends 1/4 of their day sleeping, how many hours do they spend sleeping?
Correct Answer: A
Rationale:
To calculate the number of hours a person spends sleeping when 1/4 of the day is spent sleeping, you need to find 1/4 of 24 hours. 1/4 of 24 hours is 6 hours, so the correct answer is A.
Choice B (8 hours) is incorrect because it does not correspond to 1/4 of a day.
Choice C (4 hours) is incorrect as it is half of the correct answer.
Choice D (5 hours) is incorrect as it does not match the calculation for 1/4 of a day.
Question 2 of 5
A study divides patients into 3 groups with fractions: 1/2, 1/3, and 1/6. Which group has the largest number of patients?
Correct Answer: A
Rationale: Group Alpha has the largest number of patients because it represents 1/2 of the total population, which is the highest fraction among the groups. Group Beta represents 1/3 of the population, and Group Gamma represents 1/6 of the population, making them smaller fractions in comparison. Group Delta is not mentioned in the question and is therefore unrelated to the comparison of the groups.
Question 3 of 5
Which of the following equations correctly models the relationship between x and y when y is three times x?
Correct Answer: A
Rationale: The correct equation that models the relationship between x and y when y is three times x is y = 3x. This equation represents that y is equal to three times x.
Choice B (x = 3y) incorrectly reverses the relationship, stating that x is equal to three times y.
Choice C (y = x + 3) and
Choice D (y = x / 3) do not correctly represent a relationship where y is three times x, making them incorrect choices.
Question 4 of 5
Out of 9 trips, a person chooses the longest route for 3 of them. What percentage of their trips is the longest route?
Correct Answer: B
Rationale:
To find the percentage of trips where the person chose the longest route, divide the number of longest route trips (3) by the total number of trips (9) and multiply by 100. This gives (3/9) * 100 = 33.33%, which can be rounded to 33%.
Therefore, the correct answer is B.
Choice A (0.25), C (0.5), and D (0.75) are incorrect because they do not accurately represent the percentage of trips where the longest route was chosen based on the given information.
Question 5 of 5
Veronica is making a holiday schedule. 35% of staff members will be on vacation, and 20% of the remainder are certified to work. What percentage of the staff is certified and available?
Correct Answer: A
Rationale:
To find the percentage of staff certified and available, we first calculate the percentage of staff members not on vacation, which is 100% - 35% = 65%.
Then, 20% of this group is certified to work, which is 20% of 65% = 0.20 * 65% = 13%.
Therefore, Veronica has 13% of the staff certified and available to work. The correct answer is 0.13 (or 13%).
Choice C (0.65) is incorrect because it represents the percentage of staff members not on vacation, not the percentage that is certified and available.
Choice D (0.8) is incorrect as it is not the correct percentage of staff members certified and available.
Choice B (0.13) is the correct answer, not choice A (0.07), as 0.07 represents 7%, not 13%.
