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 micrograms are in 1 milligram?

• A. 1 µg
• B. 10 µg
• C. 100 µg
• D. 1,000 µg

Correct answer: D

Rationale: The correct answer is D: 1,000 µg. To convert milligrams to micrograms, you need to multiply by 1,000 because there are 1,000 micrograms in 1 milligram. Choices A, B, and C are incorrect because they do not correctly convert milligrams to micrograms. 1 milligram is equal to 1,000 micrograms, making choice D the right answer.

3. What is 0.26 as a fraction in simplest form?

• A. 13/50
• B. 26/100
• C. 26/1000
• D. 1/4

Correct answer: A

Rationale: To convert 0.26 to a fraction, we write it as 26/100. To simplify this fraction, we divide both the numerator and the denominator by their greatest common divisor, which is 2 in this case. Dividing 26 and 100 by 2 results in 13/50. Therefore, 0.26 as a fraction in simplest form is 13/50. Choice B (26/100) is the original form of the decimal, not simplified. Choice C (26/1000) is incorrect as it doesn't match the decimal representation. Choice D (1/4) is not the equivalent fraction for 0.26.

4. How many liters (L) are equal to 1 kiloliter?

• A. 100 liters
• B. 1,000 liters
• C. 10 liters
• D. 10,000 liters

Correct answer: B

Rationale: To convert kiloliters to liters, you multiply by 1,000. Therefore, 1 kiloliter × 1,000 = 1,000 liters. Choice A (100 liters) is incorrect because it represents only 1/10th of a kiloliter. Choice C (10 liters) is incorrect as it represents only 1/100th of a kiloliter. Choice D (10,000 liters) is incorrect as it is 10 times bigger than a kiloliter.

5. What is the equivalent of 3,450 milliliters in liters (L)?

• A. 0.345 liters
• B. 3.45 liters
• C. 34.5 liters
• D. 345 liters

Correct answer: B

Rationale: To convert milliliters to liters, you need to divide by 1,000 since there are 1,000 milliliters in a liter. Therefore, 3,450 mL ÷ 1,000 = 3.45 liters. Choice A (0.345 liters) is incorrect as it incorrectly moves the decimal point. Choice C (34.5 liters) is incorrect as it overestimates the conversion. Choice D (345 liters) is incorrect as it overestimates by an order of magnitude.
