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.

Rationale: To convert kilometers to meters, you multiply by 1000 since 1 kilometer is equal to 1000 meters. Therefore, 345 kilometers x 1000 = 345,000 meters. Choice A is incorrect as it doesn't account for the conversion factor. Choice C is incorrect as it adds an extra zero. Choice D is incorrect as it adds two extra zeros. Choice B is the correct answer as it correctly converts 345 kilometers to meters by multiplying by 1000.

Correct Answer: A

Rationale: To find the result of multiplying 0.15 by 60, we simply multiply the two numbers. 0.15 x 60 = 9. This is because when you multiply a decimal by a whole number, you multiply as if the decimal point isn't there and then adjust the decimal point in the final answer. Therefore, the correct answer is A: 9. Choice B (15) is incorrect as it would be the result of multiplying 0.15 by 100. Choice C (45) is incorrect as it would be the result of multiplying 0.15 by 300. Choice D (60) is incorrect as it would be the result of multiplying 1 by 60.
