Correct Answer: B

Rationale: To convert liters to milliliters, you need to multiply by 1000 since 1 liter = 1000 milliliters. Therefore, 1.5 liters x 1000 = 1500 milliliters. So, the correct answer is B: 1,500 mL. A is incorrect as it is 10 times less than the correct answer. C is incorrect as it is 10 times less than the correct answer. D is incorrect as it is 100 times more than the correct answer.

Correct Answer: B

Rationale: The number 0.2 rounded to the nearest tenth means rounding to one decimal place. Since the digit after the tenths place is 0, we keep the tenths place as it is. Therefore, the correct answer is B: 0.2. A: 0.1 - Incorrect, this is rounding down to the nearest tenth. C: 0.3 - Incorrect, this is rounding up to the nearest tenth. D: 0.25 - Incorrect, this is rounding to the nearest hundredth, not tenth.

Correct Answer: A

Rationale: To convert mg to mcg, you multiply by 1000 since 1 mg = 1000 mcg. Therefore, 0.025 mg * 1000 = 25 mcg, which is choice A. Choice B is incorrect as it incorrectly multiplies by 10 instead of 1000. Choice C is incorrect as it incorrectly divides by 10. Choice D is incorrect as it incorrectly divides by 100 instead of multiplying by 1000.

Correct Answer: C

Rationale: To convert 0.1 liter to milliliters, we know that 1 liter equals 1000 milliliters. Therefore, 0.1 liter is equivalent to 0.1 x 1000 = 100 milliliters. Hence, the correct answer is C: 100 ml. Explanation for other choices: A: 1 ml - Incorrect, as 0.1 liter is larger than 1 ml. B: 10 ml - Incorrect, as 0.1 liter is equivalent to 100 ml, not 10 ml. D: 1000 ml - Incorrect, as 0.1 liter is smaller than 1000 ml.

Correct Answer: B

Rationale: The correct answer is B: 1000 grams. This is because there are 1000 grams in one kilogram. The prefix "kilo-" signifies 1000 in the metric system. Therefore, when converting from kilograms to grams, we multiply by 1000. The other choices are incorrect because A (100 grams) is the conversion from decagrams to grams, C (500 grams) is not the correct conversion from kilograms, and D (2000 grams) is the equivalent of 2 kilograms, not 1 kilogram. Thus, B is the correct answer.
