TEAS Practice Test Math

Correct Answer: D

Rationale: To determine the correct order of the groups, we need to compare the fractions given for each group. Group X has 1/4 of the doctors, Group Y has 1/3, and Group Z has 1/6. Comparing the fractions, we see that 1/3 is larger than 1/4 but smaller than 1/6. Therefore, Group Y has the most doctors, followed by Group X, and then Group Z. Hence, the correct order is D: Group Y, Group X, Group Z. This is because Group Y has the largest fraction of doctors, followed by Group X, and then Group Z. Choices A, B, and C can be eliminated because they do not follow the correct order based on the fractions provided.

Correct Answer: D

Rationale: The correct answer is D: 17.8 cm. To convert inches to centimeters, we use the conversion factor 1 inch = 2.54 cm. So, to find the metric equivalent of 7 inches, we multiply 7 by 2.54, which equals 17.78 cm. Rounding to one decimal place gives us 17.8 cm. Explanation for incorrect choices: A: 3.2 cm - This is incorrect as it is too small for the conversion of 7 inches. B: 2.8 cm - This is also too small for the conversion of 7 inches. C: 15.4 cm - This is incorrect as it is close to the correct answer, but not the exact conversion based on the given conversion factor.

Correct Answer: C

Rationale: To calculate the 16% gratuity on a $58.60 bill, you multiply the bill amount by 0.16 (16%). $58.60 x 0.16 = $9.38. Therefore, the estimated gratuity is $9.38 (Choice C). Incorrect Answers: A: $8.48 - Incorrect, this is not the correct calculation for a 16% gratuity on $58.60. B: $6.40 - Incorrect, this is the calculation for a 11% gratuity on $58.60. D: $7.00 - Incorrect, this is the calculation for a 12% gratuity on $58.60.

Correct Answer: C

Rationale: To find the amount of sugar needed for 0.625 of the recipe, you multiply 0.375 (original amount) by 0.625 (desired portion). 0.375 x 0.625 = 0.234375 cups. Therefore, you should use 0.234375 cups of sugar. Choice A is incorrect as it adds the original and desired portions. Choice B is close but not the correct calculation. Choice D is way off, likely a miscalculation.

Correct Answer: C

Rationale: To convert milliliters to liters, divide by 1000 since there are 1000 mL in 1 L. Here, 2500 mL ÷ 1000 = 2.5 L. Therefore, the correct answer is C (2.5 L). Choice A (0.25 L) is incorrect because the decimal point is in the wrong place. Choice B (25 L) and D (250 L) are incorrect as they are significantly higher than the actual conversion.
