Answer

### 1 cm : 1.25 km### 1 cm : 150 km### 1 cm : 5 km### 1 cm : 500 m (or 1 cm : 0.5 km)

Explanation

## Step 1: Understanding the Scale### A fractional scale of means 1 unit on the map represents 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.## Step 2: Converting 1:125000### 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.## Step 3: Converting 1:15000000### 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.## Step 4: Converting 1:500000### 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.## Step 5: Converting 1:50000### 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.
