Metric Conversions for TEAS 7

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: A

Rationale: To convert grams to milligrams, you multiply by 1000 since 1 gram = 1000 milligrams. Therefore, 0.4 grams x 1000 = 400 mg. Choice A (400 mg) is correct. Choices B, C, and D are incorrect because they do not follow the correct conversion factor of 1 gram = 1000 milligrams.

Correct Answer: C

Rationale: The correct answer is C: femto- (f) = 10^-12 meters. The prefix "femto-" represents 10^-15, not 10^-12. Therefore, choices A and D are incorrect. Choice B, nano- (n) = 10^-12, is incorrect as well because it actually represents 10^-9. The correct relationship is that femto- (f) corresponds to 10^-12 meters, making option C the right choice.

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.
