TEAS Math Practice Test

Correct Answer: C

Rationale: To find the fraction of blue shirts, we need to subtract the fractions of green and red shirts from 1 (total). Given that 1/4 are green and 1/3 are red, the fraction of blue shirts is 1 - 1/4 - 1/3 = 12/12 - 3/12 - 4/12 = 5/12. Therefore, the correct answer is C: 5/12. Choice A (1/2) is incorrect as it doesn't consider the given fractions of green and red shirts. Choice B (1/3) is incorrect as it only considers the fraction of red shirts. Choice D (1/4) is incorrect as it only considers the fraction of green shirts.

Correct Answer: D

Rationale: To find the speed in feet per second, first convert 72 miles to feet (1 mile = 5280 feet). Then, convert 90 minutes to seconds (1 minute = 60 seconds). Next, divide the distance in feet by the time in seconds to get the speed in feet per second. The correct calculation is (72 miles * 5280 feet/mile) / (90 minutes * 60 seconds/minute) = 70.4 feet per second. Choice A is too low, choice B is too high, and choice C is extremely low compared to the correct answer.

Correct Answer: A

Rationale: Step-by-step rationale: 1. Convert 1/3 to a decimal: 1 divided by 3 equals 0.3333... 2. Compare 0.5 to 0.3333...; it is evident that 0.5 is larger. 3. Therefore, 0.5 is larger than 1/3. Summary: Choice A is correct as 0.5 is greater than 1/3. Choice B is incorrect as 1/3 is smaller. Choice C is incorrect as they are not equal. Choice D is incorrect as a comparison can be made.

Correct Answer: D

Rationale: To convert a decimal to a percentage, you multiply by 100. Therefore, 0.80 * 100 = 80%. So, the correct answer is D. Choice A (40%) is incorrect because 0.80 is not equal to 0.40. Choice B (125%) is incorrect as 0.80 is less than 1. Choice C (90%) is incorrect as 0.80 is not equal to 0.90.

Correct Answer: D

Rationale: The factors of a number are the integers that can divide the number without leaving a remainder. To find the factors of 12, we start with 1 and check each integer up to 12. 1, 2, 3, 4, 6, and 12 are all factors of 12 because they divide evenly into 12. Choice D is correct because it lists all the factors of 12. Choices A, B, and C include numbers that are not factors of 12, making them incorrect.
