Practice Math TEAS TEST

Correct Answer: A

Rationale: To find the sum of three times a number and eight times a different number, we need to add 3 times the first number (3x) to 8 times the second number (8y). Therefore, the correct expression is 3x + 8y (Choice A). This choice correctly represents the operation of adding the terms. Choices B, C, and D either incorrectly combine the coefficients of x and y or use subtraction instead of addition, making them incorrect for this question.

Correct Answer: A

Rationale: The correct answer is A because a factor is a number that can be multiplied by another number to give the original number. For example, in the case of 6, factors would be 1, 2, 3, and 6. These numbers can be multiplied to get 6. Choice B is incorrect because it describes a divisor. Choice C is incorrect as it does not specifically define a factor but rather a relationship between two numbers. Choice D is incorrect as factors can be numbers less than, equal to, or greater than 1.

Correct Answer: B

Rationale: To find the median, first, sort the data set in ascending order: -3, -2, 0, 5, 10. The middle value is the median, which is 0 in this case. This is the correct answer (B). The other choices are incorrect because: A: 10 is the highest value, not the middle value. C: 5 is not the middle value when the data set is arranged in ascending order. D: 2 is not present in the data set, making it an invalid choice.

Correct Answer: A

Rationale: The correct answer is A because in a proper fraction, the numerator (top number) is less than the denominator (bottom number). This indicates a fraction that is less than 1. In an improper fraction, the numerator is greater than the denominator, representing a fraction that is equal to or greater than 1. Choice B is incorrect because it reverses the definitions of proper and improper fractions. Choice C is incorrect because it suggests that a fraction is proper if the numerator is equal to the denominator, which is incorrect. Choice D is incorrect because it defines an improper fraction as having a numerator equal to the denominator, which is not the case.

Correct Answer: A

Rationale: The correct answer is A: A shared multiple of two denominators. In order to add or subtract fractions, they must have a common denominator. This means they need to have the same bottom number. By finding the least common multiple of the denominators, you ensure that the fractions have the same base for accurate calculations. Choice B is incorrect because the common denominator is related to the denominators, not the numerators. Choice C is incorrect as the common denominator specifically refers to the bottom number in fractions. Choice D is incorrect as a common denominator may not necessarily divide evenly into both fractions, but it must be a multiple of both denominators.
