Convert 125 Meters to Kilometers: Basic Unit Conversion Problem

To convert meters to kilometers, use the conversion factor: $1 \text{ km} = 1000 \text{ m}$. Thus, $1 \text{ m} = \frac{1}{1000} \text{ km}$.

• Step 1: Identify the given measurement as $125 \text{ m}$.
• Step 2: Convert meters to kilometers by multiplying by $\frac{1}{1000}$ km/m.

Calculation:
$125 \text{ m} \times \frac{1}{1000} \text{ km/m} = 0.125 \text{ km}$.

The problem provides multiple-choice answers, and the correct answer is expressed as a fraction, so express $0.125$ as a fraction:

$0.125 = \frac{125}{1000} = \frac{1}{8}$ after simplification.

Therefore, the solution to the problem is $\frac{1}{8}$ km.
