TEAS Test Math Questions

Correct Answer: B

Rationale: To find the median, we first arrange the data set in ascending order: 3, 5, 7, 9, 11. The median is the middle value when the data is ordered, which is 7 in this case. To confirm, count the numbers: there are 5 data points, making 7 the third value from both ends. Therefore, the median of the data set is 7. Choice A (3) is incorrect because it is the smallest value in the data set. Choice C (9) is incorrect because it is the second largest value in the data set. Choice D (5) is incorrect because it is the second smallest value in the data set.

Correct Answer: C

Correct Answer: A

Rationale: To multiply fractions, you simply multiply the numerators and denominators separately. So, (3/5) * (5/8) = (3*5)/(5*8) = 15/40. However, it can be simplified to 3/8 by dividing both numerator and denominator by 5. Thus, the correct answer is A: 3/8. Choice B (3/5) is the first fraction, not the result. Choice C (15/40) is the intermediate result before simplification. Choice D (3/30) is incorrect as the numerator should be 15, not 3.

Correct Answer: A

Rationale: To find the total pounds of apples Eric buys, we multiply the pounds he buys each week (5 1/2) by the number of weeks (4). 5 1/2 * 4 = 22 pounds. Thus, the correct answer is A (22 pounds). Other choices are incorrect because they do not correctly calculate the total pounds based on the given information. B, C, and D are not the correct results of multiplying 5 1/2 by 4.

Correct Answer: C

Rationale: To find the mean, sum all values and divide by the total count. For this data set, sum = 16+18+17+15+19+14+12+11+10+16+18+17 = 183. Total count = 12. Mean = 183/12 = 15.25, which makes choice C, 16, the correct answer. Choice A, 14.25, and B, 15.25, are incorrect as they do not match the calculated mean. Choice D, 17, is incorrect as it is higher than the calculated mean value.
