Metric Conversions for TEAS 7 Questions
Question 1 of 5
What is 0.875 as a fraction?
Correct Answer: A
Rationale: To convert 0.875 to a fraction, we can write it as 875/1000 and simplify it to 7/8 by dividing both the numerator and denominator by 125. The correct answer is A (7/8). Choice B (9/10) is incorrect as it does not represent 0.875. Choices C (5/6) and D (3/4) are also incorrect fractions as they do not equal 0.875 when converted.
Question 2 of 5
How many ounces are in one pint?
Correct Answer: B
Rationale: The correct answer is B: 16 ounces. One pint is equivalent to 16 fluid ounces. This is a standard conversion in the US customary system. To arrive at this answer, you need to know that there are 2 cups in a pint and 8 fluid ounces in a cup, giving a total of 16 ounces in one pint. Choice A (12 ounces) is incorrect because it does not match the standard conversion of one pint to 16 ounces. Choice C (8 ounces) is incorrect as it represents the amount in one cup, not a pint. Choice D (20 ounces) is incorrect as it exceeds the standard conversion for one pint.
Question 3 of 5
How many centimeters are in one millimeter?
Correct Answer: B
Rationale: The correct answer is B: 0.1 cm. 1 millimeter is equal to 0.1 centimeters because there are 10 millimeters in 1 centimeter. To convert millimeters to centimeters, you divide by 10. Choice A (1/100 cm) is incorrect because 1 millimeter is not equal to 1/100 of a centimeter. Choice C (1 cm) is incorrect because 1 millimeter is smaller than 1 centimeter. Choice D (10 cm) is incorrect because 1 millimeter is not equal to 10 centimeters; it is only 0.1 centimeters.
Question 4 of 5
What is the equivalent of 1 nanometer (nm) in meters (m)?
Correct Answer: A
Rationale: To convert nanometers to meters, we need to remember that nano- is a prefix meaning 10^-9. Therefore, 1 nanometer is equal to 10^-9 meters. So, the correct answer is A: 10^-9 meters. Explanation for why other choices are incorrect: - B: 10^-6 meters is the equivalent of a micrometer, not a nanometer. - C: 10^-12 meters is the equivalent of a picometer, which is smaller than a nanometer. - D: 10^-15 meters is the equivalent of a femtometer, which is much smaller than a nanometer.
Question 5 of 5
Convert 0.20 liters to milliliters. What is the equivalent volume?
Correct Answer: A
Rationale: To convert 0.20 liters to milliliters, we know that 1 liter is equal to 1000 milliliters. Therefore, 0.20 liters = 0.20 x 1000 = 200 milliliters. So, the correct answer is A: 200 ml. Choice B (20 ml) is incorrect as it represents 0.02 liters. Choice C (2 ml) is incorrect as it represents 0.002 liters. Choice D (2000 ml) is incorrect as it is the result of incorrectly multiplying 0.20 liters by 1000 twice.
