Metric Conversions for TEAS 7

Correct Answer: B

Rationale: To convert meters to kilometers, we divide by 1,000 since 1 kilometer is equal to 1,000 meters. Therefore, 1,000 meters divided by 1,000 equals 1 kilometer. Hence, the correct answer is B: 1 km. A: 0.1 km - Incorrect. This would be the equivalent of 100 meters. C: 10 km - Incorrect. This would be the equivalent of 10,000 meters. D: 0.01 km - Incorrect. This would be the equivalent of 10 meters.

Correct Answer: B

Rationale: The correct answer is B: 2 cups in one pint. A pint is equivalent to 2 cups in the US customary system of measurement. This conversion is based on the fact that 1 pint is equal to 16 fluid ounces, and 1 cup is equal to 8 fluid ounces. Therefore, 16 fluid ounces (1 pint) divided by 8 fluid ounces (1 cup) equals 2 cups. The other choices are incorrect because they do not accurately represent the conversion between pints and cups. Choice A (1 cup) is incorrect as it does not match the conversion factor. Choices C (3 cups) and D (4 cups) are incorrect as they provide values that do not align with the correct measurement relationship between pints and cups.

Correct Answer: B

Rationale: To convert kilograms to grams, you need to multiply by 1000 since 1 kilogram is equal to 1000 grams. So, 0.75 kg * 1000 = 750 grams. Therefore, choice B (750 grams) is correct. Choice A (75 grams) is incorrect as it is a decimal point off; choice C (7,500 grams) is incorrect as it is off by a factor of 10; and choice D (75,000 grams) is incorrect as it is off by a factor of 100.

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.

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.
