1. 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.

2. What is 0.6 liters converted to milliliters?

• A. 600 ml
• B. 60 ml
• C. 6 ml
• D. 0.6 ml

Correct answer: A

Rationale: To convert 0.6 liters to milliliters, you need to multiply by 1,000 since there are 1,000 milliliters in a liter. Therefore, 0.6 liters equals 600 milliliters. Choice B (60 ml) is incorrect as it is a conversion of 0.06 liters, not 0.6 liters. Choice C (6 ml) is incorrect as it represents a conversion of 0.006 liters, not 0.6 liters. Choice D (0.6 ml) is incorrect as it is the original amount in milliliters, not the converted amount from liters.

3. Convert 0.2 liters to milliliters. What is the equivalent volume?

• 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 1,000 because there are 1,000 milliliters in a liter. So, 0.2 * 1,000 = 200 milliliters. Therefore, the correct answer is 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.

4. What is 0.075 mg converted to micrograms?

• A. 75 mcg
• B. 7.5 mcg
• C. 0.75 mcg
• D. 750 mcg

Correct answer: D

Rationale: To convert milligrams to micrograms, you need to multiply by 1000 since there are 1000 micrograms in a milligram. Therefore, to convert 0.075 mg to mcg, you would multiply 0.075 by 1000, which equals 75. Thus, the correct conversion is 750 mcg. Choice A, 75 mcg, is incorrect as it's the result if you mistakenly multiply by 10 instead of 1000. Choice B, 7.5 mcg, is incorrect as it's the result if you divide by 10 instead of multiplying by 1000. Choice C, 0.75 mcg, is incorrect as it's the result if you divide by 100 instead of multiplying by 1000.

5. What is 0.004 expressed as a ratio?

• A. 1:250
• B. 4:20
• C. 2:40
• D. 9:20

Correct answer: A

Rationale: The decimal 0.004 can be represented as a ratio of 4/1000, which simplifies to 1/250, making the ratio 1:250. The correct answer is A. Choices B, C, and D are incorrect because they do not reflect the correct conversion of 0.004 into a simplified ratio. Choice B simplifies to 1:5, Choice C simplifies to 1:20, and Choice D simplifies to 9:20, none of which accurately represent the ratio of 0.004.
