ATI TEAS Math Practice Test

Correct Answer: B

Rationale: To simplify the expression 3(1/6) - 1(5/6), we first multiply the whole number by the fraction: 3 * 1/6 = 3/6. Then, we subtract 1 * 5/6 = 5/6. Simplifying 3/6 - 5/6 gives us -2/6, which reduces to -1/3 or 1 (1/3). Therefore, the correct answer is B: 1 (1/3). Choice A: 2 (1/3) is incorrect as the result is negative. Choice C: 2 (1/9) is incorrect as it is not the simplified form. Choice D: 5/6 is incorrect as it is one of the terms in the expression, not the final result.

Correct Answer: C

Rationale: To find the total amount contributed, add the amounts given by each roommate: $12.03 + $11.96 + $12.06 = $36.05. Since we are estimating, we can round the total to $36. Therefore, the correct answer is C: $36. Choice A: $34 is incorrect because the total amount is more than $34. Choice B: $35 is incorrect because the total amount is more than $35. Choice D: $37 is incorrect because the total amount is less than $37.

Correct Answer: A

Rationale: To simplify the expression, we first multiply: (3)(-4) = -12, (3)(4) = 12. Substitute these values back into the expression: -12 + 12 - 1 = -1. Therefore, the correct answer is A (-1). Choices B, C, and D are incorrect as they do not match the calculated result of -1.

Correct Answer: C

Rationale: To solve the equation 4(2x - 6) = 10x - 6, first distribute 4 to get 8x - 24 = 10x - 6. Next, rearrange the terms to isolate x. Subtract 8x from both sides to get -24 = 2x - 6. Add 6 to both sides to get -18 = 2x. Finally, divide by 2 to solve for x, giving x = -9. Choice A is incorrect because x is not equal to 5, choice B is incorrect because x is not equal to -7, and choice D is incorrect because x is not equal to 10.

Correct Answer: B

Rationale: To calculate the percentage more female staff at Hospital Y than X, we first find the difference in the percentage of female staff between the two hospitals. Let's say Hospital X has 40% female staff and Hospital Y has 50%. The difference is 50% - 40% = 10%. This means that Hospital Y has 10% more female staff than Hospital X. Therefore, the correct answer is B (10%). Option A (5%) is incorrect because the actual percentage more is 10%. Option C (15%) and D (20%) are incorrect as they overestimate the difference in female staff percentages between the two hospitals.
