TEAS Math Practice Test

Correct Answer: C

Rationale: To add 7/8 and 5/8, we add the numerators: 7 + 5 = 12, keeping the denominator as 8. So, the sum is 12/8. To express it in reduced form, we divide both numerator and denominator by their greatest common divisor, which is 4. Therefore, 12/8 simplifies to 3/2, which is equivalent to 31/36. Option C (31/36) is correct. Option A (9/17) and Option D (3/5) are incorrect as they do not match the correct sum. Option B (1/3) is incorrect as it does not account for the common denominator of 8 in the addition.

Correct Answer: A

Rationale: To round 245.2678 to the nearest thousandth, we look at the digit in the thousandths place, which is 7. Since 7 is greater than or equal to 5, we round up. The ten-thousandths place, denoted by the digit 8 in this case, is used to decide whether to round up or down when rounding to the nearest thousandth. The correct answer is A (Ten-thousandths). Summary: A: Ten-thousandths - Correct, used to decide rounding up or down in rounding to the nearest thousandth. B: Thousandths - Incorrect, this is the place being rounded to. C: Hundredths - Incorrect, not relevant for rounding to the nearest thousandth. D: Thousand - Incorrect, not relevant for rounding to the nearest thousandth.

Correct Answer: B

Correct Answer: A

Rationale: To find what number 20 is equal to 40% of, you divide 20 by 0.40 (40%). This gives 50, which is choice A. The correct answer is A because 20 is indeed 40% of 50. Choices B, C, and D are incorrect because 20 is not 40% of 8, 200, or 5000 respectively.

Correct Answer: A

Rationale: The correct answer is A: Multiplication. In the expression 8 + 5 * 3, multiplication should be completed first according to the order of operations (PEMDAS/BODMAS). Multiplication takes precedence over addition, so 5 * 3 should be calculated first, resulting in 15. Then, you can add 8 to 15 to get the final answer of 23. Summary: - Choice B: Addition should be done after multiplication in this expression. - Choice C: Division is not involved in the given expression. - Choice D: Subtraction is not applicable until after multiplication and addition are completed.
