1. What is 0.4 grams in milligrams?

• A. 400 mg
• B. 40 mg
• C. 4 mg
• D. 4000 mg

Correct answer: A

Rationale: To convert grams to milligrams, you need to multiply by 1000 as there are 1000 milligrams in one gram. Therefore, 0.4 grams x 1000 = 400 mg. Choice A, 400 mg, is the correct answer. Choices B, C, and D are incorrect because they do not correctly apply the conversion factor of 1000 to convert grams to milligrams.

2. How many milligrams are in 2 grams?

• A. 200 mg
• B. 2,000 mg
• C. 20 mg
• D. 20,000 mg

Correct answer: B

Rationale: To convert grams to milligrams, you need to multiply by 1,000 since there are 1,000 milligrams in a gram. Therefore, 2 grams is equal to 2,000 milligrams. Choice A (200 mg) is incorrect as it represents 0.2 grams. Choice C (20 mg) is incorrect as it represents 0.02 grams. Choice D (20,000 mg) is incorrect as it represents 20 grams.

3. What is 0.125 as a fraction?

• A. 1/8
• B. 1/4
• C. 1/2
• D. 1/16

Correct answer: A

Rationale: To convert 0.125 to a fraction, we write it as 125/1000. Simplifying by dividing both the numerator and denominator by 125 gives us 1/8. Therefore, choice A (1/8) is the correct answer. Choice B (1/4) is incorrect as it represents 0.25, not 0.125. Choice C (1/2) is incorrect as it represents 0.5, not 0.125. Choice D (1/16) is incorrect as it represents 0.0625, not 0.125.

4. Convert 1.25 kilograms to grams.

• A. 12.5 grams
• B. 125 grams
• C. 1,250 grams
• D. 1250 mg

Correct answer: C

Rationale: To convert kilograms to grams, you need to multiply by 1000 since there are 1000 grams in a kilogram. Therefore, 1.25 kilograms is equal to 1.25 x 1000 = 1,250 grams. Choices A, B, and D are incorrect because they do not correctly convert kilograms to grams.

5. What is 0.5 liters converted to milliliters?

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

Correct answer: B

Rationale: To convert liters to milliliters, you need to multiply the number of liters by 1000 because there are 1000 milliliters in 1 liter. Therefore, 0.5 liters converts to 500 milliliters. Choice A (50 ml) is incorrect as it is the result of multiplying by 10 instead of 1000. Choice C (5 ml) is incorrect as it is the result of dividing by 10 instead of multiplying by 1000. Choice D (0.5 ml) is incorrect as it represents the original quantity in milliliters, not the conversion from liters.
