ATI TEAS Math Practice Test

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.

Correct Answer: A

Rationale: To simplify the expression, convert the mixed number 1 9/16 to an improper fraction: 1 * 16 + 9 / 16 = 25/16. Thus, the correct answer is A: 1 9/16. Option B (1 1/4) and Option C (2 1/8) do not represent the correct simplification of the given expression. Option D (2) is also incorrect as it does not accurately represent the simplified form of the expression.

Correct Answer: C

Rationale: To determine the correct answer, we use the ratio of mg to mL in the concentrated drops. 80 mg is in 0.8 mL, so the concentration is 100 mg per 1 mL. Since the child needs 240 mg, we divide 240 by 100 to find the volume needed, which is 2.4 mL. Therefore, the correct answer is C. Choice A (0.8 mL) is incorrect because that is the original volume, not the calculated dosage. Choice B (1.6 mL) is incorrect as it is half the correct dosage, not the full dosage of 240 mg. Choice D (3.2 mL) is incorrect as it is double the correct dosage, exceeding the required 240 mg for the child.

Correct Answer: A

Rationale: To convert 56 kilograms to pounds, we use the conversion factor that 1 kilogram is approximately 2.2 pounds. So, 56 kg x 2.2 = 123.2 pounds. Since we are asked for the approximate weight in pounds, we round it to the nearest whole number, which is 123 pounds. Summary: - A (123 pounds) is correct because it is the accurate conversion of 56 kilograms to pounds. - B (110 pounds), C (156 pounds), and D (137 pounds) are incorrect as they do not correctly convert 56 kilograms to pounds using the conversion factor.

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.
