TEAS Practice Test Math

Correct Answer: A

Rationale: To find the least common denominator (LCD), we need to find the least common multiple (LCM) of the denominators. The denominators are 2, 3, and 5. The LCM of 2, 3, and 5 is 30, which is the smallest number that all three denominators divide into evenly. Therefore, the correct answer is A: 30. Choice B: 25 is not the correct answer because it is not divisible by 2, 3, and 5. Choice C: 7 is not the correct answer because it is not divisible by 2, 3, and 5. Choice D: 19 is not the correct answer because it is not divisible by 2, 3, and 5.

Correct Answer: A

Rationale: The correct answer is A: One. When the number 1 is raised to any power, the result is always 1. This is because any number raised to the power of 1 is equal to that number itself. In this case, 1 raised to any power will always be 1. Summary: Choice B (Itself) is incorrect because raising 1 to any power does not result in the number itself, but always in 1. Choice C (Zero) is incorrect as any number raised to the power of 0 is 1, not 0. Choice D (Two) is incorrect as it is not possible for 1 raised to any power to equal 2.

Correct Answer: A

Rationale: To calculate the number of months, we first subtract the down payment from the total cost to get the remaining balance: $1570 - $400 = $1170. Then, we divide the remaining balance by the monthly payment to determine the number of months: $1170 / $100 = 11.7 months. Since we cannot have partial months in this case, we round up to the nearest whole number, giving us 12 months. Therefore, the correct answer is A (12 months). Choice B (16 months) is too high, Choices C (15 months) and D (11 months) are too low based on the calculations.

Correct Answer: D

Rationale: To determine the correct order of the groups, we need to compare the fractions given for each group. Group X has 1/4 of the doctors, Group Y has 1/3, and Group Z has 1/6. Comparing the fractions, we see that 1/3 is larger than 1/4 but smaller than 1/6. Therefore, Group Y has the most doctors, followed by Group X, and then Group Z. Hence, the correct order is D: Group Y, Group X, Group Z. This is because Group Y has the largest fraction of doctors, followed by Group X, and then Group Z. Choices A, B, and C can be eliminated because they do not follow the correct order based on the fractions provided.

Correct Answer: A

Rationale: The correct answer is A because an integer is defined as a whole number that can be positive, negative, or zero. Integers do not include fractions or decimals (eliminating choices B and C) or percentages (eliminating choice D). Integers are the set of numbers {..., -3, -2, -1, 0, 1, 2, 3, ...} and do not include numbers with decimal points or fractions. Therefore, choice A is the only option that accurately describes what defines an integer.
