Convertis l'échelle fractionnaire en échelle verbale: 1:125000 __ 1:15000000 __ 1:500000 __ 1:50000 __

## Step 1: Understanding the Scale<br />### A fractional scale of $1:x$ means 1 unit on the map represents $x$ units on the ground. To convert to a verbal scale, we need to choose appropriate units (cm, m, km) for both the map and the ground.<br /><br />## Step 2: Converting 1:125000<br />### 1 cm on the map represents 125000 cm on the ground. 125000 cm = 1250 m = 1.25 km. So, the verbal scale is 1 cm : 1.25 km.<br /><br />## Step 3: Converting 1:15000000<br />### 1 cm on the map represents 15000000 cm on the ground. 15000000 cm = 150000 m = 150 km. So, the verbal scale is 1 cm : 150 km.<br /><br />## Step 4: Converting 1:500000<br />### 1 cm on the map represents 500000 cm on the ground. 500000 cm = 5000 m = 5 km. So the verbal scale is 1 cm : 5 km.<br /><br />## Step 5: Converting 1:50000<br />### 1 cm on the map represents 50000 cm on the ground. 50000 cm = 500 m = 0.5 km. So the verbal scale is 1 cm : 0.5 km or 1 cm : 500 m.
