TEAS Math Practice Test

Correct Answer: C

Rationale: The number -4 is classified as real, rational, and integer. 1. Real: -4 is a real number as it exists on the number line. 2. Rational: -4 can be expressed as -4/1, which is a ratio of two integers. 3. Integer: -4 is a whole number that includes negative numbers. Therefore, the correct answer is C. Summary: A: Incorrect, as it includes "natural," which does not apply to negative numbers. B: Incorrect, as it includes "natural," which is only positive integers. D: Incorrect, as -4 is rational, not irrational.

Correct Answer: A

Rationale: To express 18/5 as a reduced mixed number, we divide 18 by 5 which equals 3 with a remainder of 3. So, 18/5 = 3 3/5. This mixed number is in its simplest form. Choice A is correct. Choices B, C, and D are incorrect as they do not represent the correct division of 18 by 5 resulting in the remainder of 3.

Correct Answer: A

Rationale: To solve for y, first isolate y by adding 7 to both sides of the equation: 5y - 7 + 7 = 13 + 7. This simplifies to 5y = 20. Then, divide by 5 on both sides to find y = 4. Thus, the correct answer is A: 4. Choices B, C, and D are incorrect as they do not satisfy the equation 5y - 7 = 13.

Correct Answer: A

Rationale: To divide 52 by 27, we get 1 with a remainder of 25. Then, when we divide 51 by 27, we get 1 with a remainder of 24. Therefore, the correct answer is A: 52/27, as it represents the result of the division without simplification. Choices B, C, and D are incorrect as they do not accurately represent the division results obtained.

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.
