1. Convert 0.2 liters to milliliters.

• A. 20 ml
• B. 200 ml
• C. 2 ml
• D. 2000 ml

Correct answer: B

Rationale: To convert 0.2 liters to milliliters, you need to multiply by 1000 because there are 1000 milliliters in 1 liter. Therefore, 0.2 liters x 1000 = 200 ml. Choice A (20 ml) is incorrect because it represents 0.02 liters, not 0.2 liters. Choice C (2 ml) is incorrect as it represents 0.002 liters. Choice D (2000 ml) is incorrect as it represents 2 liters, not 0.2 liters.

2. What is 0.2 mg converted to mcg?

• A. 200 mcg
• B. 20 mcg
• C. 2000 mcg
• D. 2 mcg

Correct answer: A

Rationale: To convert milligrams (mg) to micrograms (mcg), you need to multiply by 1000 because there are 1000 micrograms in 1 milligram. Therefore, 0.2 mg * 1000 = 200 mcg. This is the correct conversion. Choice B (20 mcg) is incorrect because it does not account for multiplying by 1000. Choice C (2000 mcg) is incorrect as it mistakenly multiplies by 10 instead of 1000. Choice D (2 mcg) is incorrect as it does not involve any conversion from milligrams to micrograms.

3. What is 0.5 liters in ml?

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

Correct answer: A

Rationale: To convert liters to milliliters, you need to multiply by 1000 since 1 liter is equal to 1000 milliliters. Therefore, 0.5 liters equals 500 milliliters. This conversion is commonly used in various fields such as cooking, medicine, and science. Choice B, 50 ml, is incorrect as it represents 0.05 liters, not 0.5 liters. Choice C, 5 ml, is even smaller and represents 0.005 liters. Choice D, 0.5 ml, is incorrect as it is a tenth of the correct conversion.

4. What is 0.4 divided by 40?

• A. 1/100
• B. 1/1000
• C. 1/400
• D. 1/40000

Correct answer: B

Rationale: The calculation of 0.4 divided by 40 results in 0.01, which can be expressed as 1/100. This fraction is the correct representation of the division of 0.4 by 40. Choice A, 1/100, is the correct answer as it accurately reflects the division. Choices C and D, 1/400 and 1/40000 respectively, do not correctly represent the division operation performed on 0.4 and 40, leading to incorrect results and are therefore not the correct answers.

5. How many milliliters are in 0.5 liters?

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

Correct answer: A

Rationale: To convert from liters to milliliters, you need to multiply by 1000 since there are 1000 milliliters in a liter. Therefore, 0.5 liters x 1000 = 500 milliliters. This conversion is common in various contexts where different units of volume are used. Choices B, C, and D are incorrect as they do not reflect the correct conversion factor from liters to milliliters.
