TEAS Math Practice Test

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.

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: A

Rationale: To convert 3 5/7 to an improper fraction, multiply the whole number (3) by the denominator (7) and add the numerator (5) to get 26. The denominator remains the same, resulting in 26/7. This is the correct answer because it represents the mixed number 3 5/7 in fraction form. Choice B (21/7) simplifies to 3, which is the whole number part of the mixed number. Choice C (22/7) is equivalent to the approximation of π and not the correct conversion of 3 5/7. Choice D (26/5) is incorrect as it does not represent the mixed number 3 5/7 accurately.

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 express 0.0523 as a fraction, we need to consider the decimal places. Since 0.0523 has 4 decimal places, we place the digits after the decimal point over the place value of the last digit, which is 10000. Therefore, the fraction is 523/10000, making choice A the correct answer. Choices B, C, and D are incorrect as they do not reflect the correct placement of decimal digits relative to the decimal point and the corresponding place value.
