TEAS Practice Test Math

1. How do you convert yards to feet, and feet to yards?

A. Multiply yards by 3 to get feet; divide feet by 3 to get yards
B. Multiply yards by 2 to get feet; divide feet by 2 to get yards
C. Multiply yards by 1.5 to get feet; divide feet by 1.5 to get yards
D. Multiply yards by 4 to get feet; divide feet by 4 to get yards

Correct answer: A

Rationale: To convert yards to feet, you need to know that 1 yard is equal to 3 feet. Therefore, to convert yards to feet, you multiply the number of yards by 3. To convert feet to yards, you divide the number of feet by 3. Choice A correctly states that you should multiply yards by 3 to get feet and divide feet by 3 to get yards. Choices B, C, and D provide incorrect conversion factors, leading to inaccurate results.

2. Which percentage is greatest?

A. The percentage of Asian Americans among the staff at Hospital X
B. The percentage of staff members who have been on staff for 10-15 years at Hospital X
C. The percentage of Doctors among the staff at Hospital X and Hospital Y
D. The percentage of staff with 1-4 complaints among the staff at Hospital Y

Correct answer: C

Rationale: To determine the highest percentage, we need to calculate each option. The percentage in answer A is: 50 / 250 x 100 = 20%. The percentage in answer B is: 57 / 250 x 100 = 22.8%. The percentage in answer C is: (74 + 55) / 433 x 100 = 29.8%. The percentage in answer D is: 21 / 183 x 100 = 11.5%. Therefore, the correct answer is C, as it has the highest percentage of doctors among the staff at both hospitals. Choices A, B, and D are incorrect as they have lower percentages compared to choice C.

3. In a study of the average weight of babies at different time intervals after birth, the babiesâ€™ measured weight is which of the following variables?

A. Independent
B. Control
C. Dependent
D. Constant

Correct answer: C

Rationale: The baby's measured weight is the dependent variable as it depends on the time intervals.

4. Which is bigger, a mile or a kilometer? What's the conversion factor?

A. Mile is bigger; 1 mile is 1.609 km
B. Kilometer is bigger; 1 km is 1.609 miles
C. Mile is bigger; 1 mile is 1.5 km
D. Kilometer is bigger; 1 km is 2 miles

Correct answer: A

Rationale: A mile is bigger than a kilometer. The correct conversion factor is 1 mile = 1.609 km. This means that one mile is equivalent to approximately 1.609 kilometers. Choice B is incorrect because a mile is bigger than a kilometer, and the conversion is not 1 km = 1.609 miles. Choice C is incorrect as the conversion factor provided is inaccurate; 1 mile is not equal to 1.5 km. Choice D is incorrect as it states that a kilometer is bigger, which is not true according to the actual conversion factor.

5. A teacher earns $730.00 per week before any tax deductions. The following taxes are deducted each week: $72.00 federal income tax, $35.00 state income tax, and $65.00 Social Security tax. How much will the teacher make in 4 weeks after taxes are deducted?

A. $2,250.00
B. $2,550.00
C. $2,400.00
D. $2,232.00

Correct answer: D

Rationale: After deducting $172 weekly for taxes ($72 + $35 + $65), the teacher's net weekly income is $558. Over 4 weeks, the total income is $2,232.00. Choice A is incorrect as it does not account for the taxes deducted. Choice B is incorrect as it overestimates the income by not deducting the taxes. Choice C is incorrect as it also does not consider the tax deductions.
