TEAS Math Practice Test

Correct Answer: A

Rationale: To round 8.067 to the nearest tenth, we look at the hundredth place, which is 6. Since 6 is equal to or greater than 5, we round the digit in the tenths place up by 1. Therefore, 8.067 rounded to the nearest tenth is 8.1. Choice A is correct because it correctly follows the rounding rule. Choice B is incorrect as it is a duplicate of Choice A. Choice C is incorrect as it rounds down to the nearest whole number, not the nearest tenth. Choice D is incorrect as it rounds up to the hundredth place, not the nearest tenth.

Correct Answer: B

Rationale: To convert 1.25 to a fraction, we note that the decimal has two decimal places. To convert it to a fraction, we write 1.25 as 125/100. Simplifying by dividing both numerator and denominator by 25, we get 5/4. Therefore, the correct answer is B: 5/4. A: 1 1/4 is the mixed number form of 5/4. C: 4/5 is the reciprocal of the correct answer. D: 25/20 is not simplified; it should be reduced to 5/4.

Correct Answer: C

Rationale: To find the sixth number, we can first calculate the sum of all six numbers by multiplying the average (6) by the total count (6), which equals 36. Since the sum of five numbers is 25, the sixth number can be found by subtracting 25 from 36, giving us 11 (Choice C). Other choices are incorrect because they do not satisfy the conditions given in the question. Choice A, 8, would make the sum of six numbers less than 36. Choice B, 10, would also make the sum less than 36. Choice D, 12, would make the sum greater than 36. Thus, the correct answer is C (11).

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.
