TEAS Practice Test Math

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.

Correct Answer: A

Rationale: To solve the equation 3(x-2) = 12 for x: 1. Distribute the 3 to both terms inside the parentheses: 3x - 6 = 12 2. Add 6 to both sides: 3x = 18 3. Divide by 3: x = 6 Choice A (6) is correct. Choice B (-2) results in x = 4, not 6. Choice C (-4) results in x = 2, not 6. Choice D (2) results in x = 8, not 6.

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: A

Rationale: The correct answer is A because an equivalent fraction is a fraction that represents the same value as another fraction. To find an equivalent fraction, you can multiply or divide both the numerator and denominator by the same number. This maintains the fraction's value while changing its appearance. Choices B and C are incorrect because the size of a fraction is not determined by its equivalent status. Choice D is incorrect because equivalent fractions can have different numerators.

Correct Answer: C

Rationale: To convert a percentage to a decimal, you divide by 100. In this case, 87.5% divided by 100 is 0.875. Therefore, choice C, 0.875, is the correct decimal form of 87.5%. Choices A and B are incorrect as they do not represent the correct decimal value. Choice D, 8.75, is also incorrect as it is the decimal form of 875%.
