1. How many centimeters are in one millimeter?

• A. 1/100 cm
• B. 0.1 cm
• C. 1 cm
• D. 10 cm

Correct answer: B

Rationale: The correct answer is B: 0.1 cm. One millimeter is equal to 0.1 centimeters, not 1/100th cm as mentioned in choice A. Choice C, 1 cm, is incorrect as a millimeter is smaller than a centimeter. Choice D, 10 cm, is incorrect as it incorrectly magnifies the conversion, making a millimeter larger than a centimeter. Therefore, the accurate conversion is that one millimeter equals 0.1 centimeters.

2. 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.

3. Convert 3,450 grams to milligrams (mg).

• A. 34,500 mg
• B. 3,450,000 mg
• C. 3,450 mg
• D. 3,450,000 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, 3,450 grams × 1,000 = 3,450,000 milligrams. Choice A (34,500 mg) is incorrect because it represents the result for converting grams to milligrams by a factor of 10 (not 1,000). Choice C (3,450 mg) is incorrect as it represents the original amount in grams, not the converted amount to milligrams. Choice D (3,450,000 mg) is incorrect as it is the same as the correct answer but with the comma in the wrong place, which would imply converting kilograms to milligrams rather than grams to milligrams.

4. 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.

5. What is 0.075 mg in mcg?

• A. 0.075 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 1 mg = 1000 mcg. Therefore, 0.075 mg equals 75 * 1000 = 750 mcg. The correct answer is 750 mcg. Choices A, B, and C are incorrect because they do not apply the correct conversion factor of 1000. It is essential to understand these conversions, especially in medical settings where accurate dosing is crucial to avoid errors and ensure patient safety.
