Metric Conversions for TEAS 7

Correct Answer: A

Rationale: To convert 0.20 liters to milliliters, we know that 1 liter is equal to 1000 milliliters. Therefore, 0.20 liters = 0.20 x 1000 = 200 milliliters. So, the correct answer is A: 200 ml. Choice B (20 ml) is incorrect as it represents 0.02 liters. Choice C (2 ml) is incorrect as it represents 0.002 liters. Choice D (2000 ml) is incorrect as it is the result of incorrectly multiplying 0.20 liters by 1000 twice.

Correct Answer: A

Rationale: The correct answer is A: 500 ml. To convert liters to milliliters, you multiply by 1000 because there are 1000 milliliters in 1 liter. So, 0.5 liter x 1000 = 500 ml. Choice B, 50 ml, is 10 times less than the correct answer. Choice C, 5 ml, is 100 times less than the correct answer. Choice D, 0.5 ml, is 1000 times less than the correct answer.

Correct Answer: A

Rationale: To convert grams to milligrams, you need to multiply by 1000 since there are 1000 milligrams in 1 gram. So, 0.04 grams x 1000 = 40 mg. Therefore, the correct answer is A. Choice B is incorrect because it's 10 times smaller than the correct answer. Choice C is incorrect because it's 100 times larger than the correct answer. Choice D is incorrect because it's 100 times smaller than the correct answer.

Correct Answer: A

Rationale: To convert 0.20 liters to milliliters, we know that 1 liter is equal to 1000 milliliters. Therefore, 0.20 liters = 0.20 x 1000 = 200 milliliters. So, the correct answer is A: 200 ml. Choice B (20 ml) is incorrect as it represents 0.02 liters. Choice C (2 ml) is incorrect as it represents 0.002 liters. Choice D (2000 ml) is incorrect as it is the result of incorrectly multiplying 0.20 liters by 1000 twice.

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.
