1. How many kilometers (km) is equivalent to 1,000 meters?

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

Correct answer: B

Rationale: To convert meters to kilometers, the conversion factor is 1 kilometer = 1,000 meters. Therefore, to find how many kilometers are in 1,000 meters, you divide 1,000 by 1,000, which equals 1 kilometer. Choice A (0.1 km), Choice C (10 km), and Choice D (0.01 km) are incorrect because they do not correctly represent the conversion of 1,000 meters to kilometers.

2. Where was the metric system developed?

• A. Germany
• B. France
• C. Italy
• D. Spain

Correct answer: B

Rationale: The metric system was developed in France during the 1790s as a standardized system of measurement. This choice is correct because the metric system originated in France. Germany, Italy, and Spain did not play a role in the development of the metric system, making choices A, C, and D incorrect.

3. 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.

4. How many grams are in 1 kilogram?

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

Correct answer: C

Rationale: The correct answer is C: 1,000 grams. The metric system follows a logical conversion where 1 kilogram is equal to 1,000 grams. This conversion is a fundamental concept in understanding units of measurement. Choices A, B, and D are incorrect because they do not accurately reflect the conversion between kilograms and grams. Option A (10 grams) is incorrect as it represents 1/100th of the correct conversion. Option B (100 grams) is also incorrect as it represents 1/10th of the correct conversion. Option D (10,000 grams) is significantly higher than the actual conversion, making it incorrect. Understanding these basic unit conversions is essential for various fields where precise measurements are necessary.

5. 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.
