TEAS Test Sample Math Questions

Correct Answer: A

Rationale: To divide fractions, we multiply the first fraction by the reciprocal of the second. So, (4/3) ÷ (9/13) = (4/3) x (13/9) = 52/27. The correct answer is A, 52/27, as it follows the correct procedure of dividing fractions. The other choices are incorrect because they do not result from the proper operation of dividing fractions.

Correct Answer: D

Rationale: To express 8 3/7 as an improper fraction, we multiply the whole number (8) by the denominator of the fraction (7), then add the numerator (3) to get the numerator of the improper fraction. So, 8 * 7 + 3 = 59. The denominator remains the same, so the improper fraction is 59/7. Explanation of other choices: A: 11/7 - Incorrect. This is the sum of the whole number and fraction as a mixed number, not an improper fraction. B: 21/8 - Incorrect. This doesn't represent 8 3/7 as an improper fraction. C: 5/3 - Incorrect. This is a completely different fraction and does not represent 8 3/7.

Correct Answer: A

Rationale: To round 8.067 to the nearest tenth, we look at the digit in the hundredths place, which is 6. Since 6 is 5 or greater, we round up the digit in the tenths place (0) by 1. Therefore, 8.067 rounded to the nearest tenth is 8.1 (choice B). Choice A, 8.07, is incorrect because we need to round up to 8.1. Choice C, 8, is incorrect because it is rounding down to the nearest whole number. Choice D, 8.11, is incorrect because it is rounding to the nearest hundredth, not the nearest tenth.

Correct Answer: C

Rationale: To find what fraction the fourth person pays, we first calculate the sum of fractions paid by the first three people: 1/5 + 1/3 + 1/12 = 12/60 + 20/60 + 5/60 = 37/60. The total bill is 1, so the fourth person pays 1 - 37/60 = 23/60. Therefore, the correct answer is C (47/60). Choice A (1/4) is incorrect as it does not consider the fractions paid by the first three people. Choice B (13/60) is incorrect as it is the sum of the fractions paid by the first three people, not what the fourth person pays. Choice D (1/4) is a duplicate of choice A and is also incorrect.

Correct Answer: B

Rationale: To find the sum of 0.75 and 0.625, you add the two numbers together: 0.75 + 0.625 = 1.375. Therefore, the correct answer is B. Choice A (0.875) is incorrect because it is the sum of 0.75 and 0.125. Choice C (1.625) is incorrect because it is the sum of 0.75 and 0.875. Choice D (0.125) is incorrect as it is the sum of 0.75 and -0.625.
