1. Convert 100 grams to kilograms.

• A. 0.1 kg
• B. 1 kg
• C. 10 kg
• D. 0.01 kg

Correct answer: A

Rationale: To convert grams to kilograms, you need to divide by 1000 since there are 1000 grams in a kilogram. So, 100 grams divided by 1000 equals 0.1 kilograms, making choice A the correct answer. Choices B, C, and D are incorrect because they do not involve the correct conversion factor or calculation. Choice B of 1 kg is the equivalent of 1000 grams, which is 10 times the given value of 100 grams, making it too large. Choice C of 10 kg is 100 times the given value, and choice D of 0.01 kg is 10 times smaller than the correct conversion.

2. How many milligrams (mg) are equal to 1 gram?

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

Correct answer: B

Rationale: To convert grams to milligrams, you need to multiply by 1,000 because there are 1,000 milligrams in 1 gram. Therefore, 1 gram × 1,000 = 1,000 milligrams. Choice A (100 mg) is incorrect as it represents 0.1 grams, not 1 gram. Choice C (1 mg) is incorrect as it represents a fraction of a gram. Choice D (10,000 mg) is incorrect as it is 10 times more than the correct conversion.

3. What is the equivalent of 255.0 pounds in kilograms (1 kg = 2.205 lbs)?

• A. 115.7 kg
• B. 126.0 kg
• C. 115.8 kg
• D. 115.6 kg

Correct answer: D

Rationale: To convert pounds to kilograms, you need to divide the weight in pounds by 2.205 (1 kg = 2.205 lbs). Therefore, 255.0 pounds divided by 2.205 equals 115.6 kilograms. This results in choice D being the correct answer. Choices A, B, and C are incorrect as they do not reflect the accurate conversion calculation from pounds to kilograms.

4. What is 0.5 x 200?

• A. 100
• B. 50
• C. 150
• D. 200

Correct answer: A

Rationale: To find the product of 0.5 and 200, you multiply the two numbers, which equals 100. The correct answer is A. Choice B, 50, is the result of multiplying 0.5 by 100 instead of 200. Choice C, 150, is the result of adding 0.5 and 200 instead of multiplying them. Choice D, 200, is the second number in the multiplication operation and not the correct product.

5. In the metric system, what factor does the prefix kilo- represent?

• A. 10^3
• B. 10^2
• C. 10^4
• D. 10^6

Correct answer: A

Rationale: The prefix 'kilo-' in the metric system signifies a factor of 1000, which is equivalent to 10^3. Therefore, when using the prefix 'kilo-', it implies multiplying the base unit by 1000. For instance, one kilometer is equal to 1000 meters. Choices B, C, and D are incorrect as they do not accurately represent the factor associated with the prefix 'kilo-'.
