1. How many quarts are equivalent to 2 liters?

• A. 1.06 quarts
• B. 0.5 quarts
• C. 2.1 quarts
• D. 4 quarts

Correct answer: A

Rationale: To convert liters to quarts, we know that 1 liter is approximately equal to 1.06 quarts. Therefore, 2 liters would be around 2.12 quarts. However, for practical purposes, it's often rounded to 2.1 quarts. Option A, '1.06 quarts,' is the closest and most accurate approximation. Option B, '0.5 quarts,' is incorrect as it represents half of the actual conversion. Option C, '2.1 quarts,' is close but slightly higher than the actual conversion. Option D, '4 quarts,' is double the correct conversion and is therefore incorrect.

2. What is 0.1 mg to mcg?

• A. 100 mcg
• B. 10 mcg
• C. 1000 mcg
• D. 1 mcg

Correct answer: A

Rationale: To convert milligrams to micrograms, you need to multiply by 1000. Therefore, 0.1 mg is equal to 100 mcg. This conversion is commonly used in medical calculations. Choice B (10 mcg) is incorrect because it would be the conversion from milligrams to micrograms if multiplied by 100, not 10. Choice C (1000 mcg) is incorrect as it would be the conversion from grams to micrograms if multiplied by 1000. Choice D (1 mcg) is incorrect as it represents the original unit without conversion.

3. What is 0.3 as a fraction in simplest form?

• A. 3/10
• B. 1/3
• C. 1/4
• D. 1/5

Correct answer: A

Rationale: To convert 0.3 to a fraction, we take 0.3 and express it as 3/10. This fraction is already in its simplest form because 3 and 10 do not have any common factors other than 1. Choice B, 1/3, is incorrect as it represents a different value. Choice C, 1/4, and Choice D, 1/5, are also incorrect as they do not match the equivalent fraction for 0.3.

4. In the metric system, what factor does the prefix kilo- represent?

• A. 10^3
• B. 10^2
• C. 10^4
• D. 10^6

Correct answer: A

Rationale: The prefix 'kilo-' in the metric system signifies a factor of 1000, which is equivalent to 10^3. Therefore, when using the prefix 'kilo-', it implies multiplying the base unit by 1000. For instance, one kilometer is equal to 1000 meters. Choices B, C, and D are incorrect as they do not accurately represent the factor associated with the prefix 'kilo-'.

5. What is 0.5 liters in ml?

• A. 500 ml
• B. 50 ml
• C. 5 ml
• D. 0.5 ml

Correct answer: A

Rationale: The correct answer is A: 500 ml. To convert liters to milliliters, you multiply the number of liters by 1000 because 1 liter is equal to 1000 milliliters. Therefore, 0.5 liters x 1000 = 500 milliliters. Choices B, C, and D are incorrect because they do not correctly convert 0.5 liters to milliliters based on the conversion factor of 1000 ml per liter.
