1. What is the equivalent of 35.4 centimeters in kilometers (km)?

• A. 0.00354 km
• B. 0.000354 km
• C. 0.00345 km
• D. 0.0345 km

Correct answer: B

Rationale: To convert centimeters to kilometers, you need to divide by 100,000 since there are 100,000 centimeters in a kilometer. Therefore, 35.4 cm ÷ 100,000 = 0.000354 km. Choice A (0.00354 km) is incorrect as it represents dividing by 10,000, not 100,000. Choice C (0.00345 km) is incorrect as the last digit is different from the correct answer. Choice D (0.0345 km) is incorrect as it represents dividing by 1,000, not by 100,000.

2. What is 0.875 as a fraction?

• A. 7/8
• B. 9/10
• C. 5/6
• D. 3/4

Correct answer: A

Rationale: To convert 0.875 to a fraction, you can write it as 875/1000. Simplifying this fraction by dividing the numerator and denominator by their greatest common divisor, which is 125, gives you 7/8. Therefore, the correct answer is 7/8. Choice B (9/10), Choice C (5/6), and Choice D (3/4) are incorrect as they do not represent the fraction equivalent of 0.875.

3. 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.

4. How many milliliters are there in 0.5 liters?

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

Correct answer: A

Rationale: To convert liters to milliliters, you need to multiply by 1000 since there are 1000 milliliters in a liter. Therefore, 0.5 liters is equal to 500 milliliters. Choices B, C, and D are incorrect because they do not reflect the correct conversion from liters to milliliters.

5. What is the value of one femtometer (fm) in meters?

• A. 10^-15 meters
• B. 10^-9 meters
• C. 10^-12 meters
• D. 10^-18 meters

Correct answer: A

Rationale: A femtometer is equivalent to 10^-15 meters. The prefix 'femto-' signifies a factor of one quadrillionth (10^-15), making choice A the correct answer. Choice B (10^-9 meters) represents a nanometer, not a femtometer. Choice C (10^-12 meters) corresponds to a picometer, not a femtometer. Choice D (10^-18 meters) is even smaller than a femtometer and refers to an attometer, not a femtometer.
