ABDUL JILANI BASHA · Accepted Answer

## CORE INFORMATION
✓ **Answer**: Option D
## CONCEPT FRAMEWORK
	**Primary Concept**: Unit Conversion
	**Related Topics**: Metric System, Length Measurement
	**Prerequisites**: Understanding of metric prefixes (centi-, kilo-), Relationship between centimeter and meter, meter and kilometer
## SOLUTION PATHWAY
**Given Information**:
	* Length in centimeters: 100 cm
	* Target unit: kilometers
**Method & Steps**:
	1. Convert centimeters to meters
		Reasoning: There are 100 centimeters in 1 meter.
		Formula/Rule: $1 	ext{ m} = 100 	ext{ cm}$ or $1 	ext{ cm} = \frac{1}{100} 	ext{ m}$
	2. Convert meters to kilometers
		Working: $100 	ext{ cm} = 100 	imes \frac{1}{100} 	ext{ m} = 1 	ext{ m}$ and $1 	ext{ m} = \frac{1}{1000} 	ext{ km}$
		Key Point: There are 1000 meters in 1 kilometer.
	3. Calculate the equivalent in kilometers
		Result: $1 	ext{ m} = 1 	imes \frac{1}{1000} 	ext{ km} = 0.001 	ext{ km}$
		Verification: The conversion is correct.
 ## OPTION ANALYSIS
[A] :x: Incorrect. 0.01 km is equivalent to 10 meters or 1000 cm.
[B] :x: Incorrect. 0.1 km is equivalent to 100 meters or 10000 cm.
[C] :x: Incorrect. 1 km is equivalent to 1000 meters or 100000 cm.
[D] ✓: Correct. 100 cm is equal to 0.001 km.
 ## LEARNING AIDS
	**Common Mistakes**:
		1.[Error 1]: Incorrectly applying conversion factors. Always ensure you are dividing or multiplying by the correct number.
		2.[Error 2]: Confusing the prefixes. Remember that 'centi-' means 1/100 and 'kilo-' means 1000.
	**Quick Tips**:
		1.[Helpful shortcut]: When converting from a smaller unit to a larger unit, you typically divide. When going from larger to smaller, you typically multiply.
		2.[Memory aid]: To remember the conversion from cm to km, think: cm -> m (divide by 100) -> km (divide by 1000). Total division is by 100,000.
