Metric Conversions for TEAS 7

Correct Answer: B

Rationale: The correct answer is B: Liters. Liters are the base unit for liquid volume in the metric system because they are used to measure larger volumes, making them more practical for everyday use. Milliliters are a smaller unit derived from liters, making them not the base unit. Gallons are not part of the metric system; they are commonly used in the imperial system. Choosing Liters again reinforces that it is the correct base unit for liquid volume in the metric system.

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.

Correct Answer: B

Rationale: To convert liters to milliliters, you multiply by 1000 because 1 liter equals 1000 milliliters. Therefore, 0.09 liters x 1000 = 90 milliliters. The correct answer is B. Choice A is incorrect as it does not convert liters to milliliters. Choice C is incorrect as it is 10 times the correct answer. Choice D is incorrect as it is 1/10 of the correct answer.

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: C

Rationale: To convert from centimeters to millimeters, you multiply by 10 since there are 10 millimeters in 1 cm. Therefore, to find how many millimeters are in 0.75 cm, you multiply 0.75 by 10, which equals 7.5 mm. Therefore, the correct answer is C: 75 mm. Choice A: 7.5 mm is the result of the correct conversion. Choice B: 0.75 mm is incorrect as it's the original value, not the converted value. Choice D: 75 cm is incorrect as the question asks for millimeters, not centimeters.
