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 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: D

Rationale: To convert 0.075 mg to micrograms, you need to multiply by 1000 since there are 1000 micrograms in a milligram. So, 0.075 mg * 1000 = 75 mcg. Therefore, the correct answer is D: 750 mcg. Choices A, B, and C are incorrect as they do not correctly convert milligrams to micrograms.

Correct Answer: A

Rationale: The correct answer is A: G. The prefix "giga" represents 10^9 in the International System of Units (SI). The symbol for "giga" is a capital letter G. It is used to denote a factor of one billion. Choice B, m, represents the prefix "milli" which is 10^-3. Choice C, Gg, is not a standard representation of the prefix "giga." Choice D, g, represents the unit of mass "gram," not the prefix "giga." Therefore, the correct notation for the prefix "giga" is A: G.

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.
