To express the earnings of the Skosana children as a ratio in its simplest form, follow these steps:

1. **List the Earnings:**
   - Eldest child: R270
   - Middle child: R180
   - Youngest child: R90

2. **Form the Initial Ratio:**
   $$
   270 : 180 : 90
   $$

3. **Find the Greatest Common Divisor (GCD):**
   - The GCD of 270, 180, and 90 is **90**.

4. **Simplify Each Term by Dividing by the GCD:**
   $$
   \frac{270}{90} : \frac{180}{90} : \frac{90}{90} = 3 : 2 : 1
   $$

**Simplest Form of the Ratio:**
$$
3 : 2 : 1
$$

This means for every **3 parts** that the eldest child earns, the middle child earns **2 parts**, and the youngest child earns **1 part**.
The ratio of the children's earnings is 3:2:1.
