To solve the problem of finding the cost of 5 oranges when 8 oranges cost Rs 20.80, we can follow these steps:

### Step 1: Find the cost of 1 orange
We know the cost of 8 oranges is Rs 20.80. To find the cost of 1 orange, we divide the total cost by the number of oranges.

\[ \text{Cost of 1 orange} = \frac{\text{Cost of 8 oranges}}{8} = \frac{20.80}{8} \]

### Step 2: Calculate the cost of 1 orange
Now, we perform the division:

\[ \frac{20.80}{8} = 2.60 \]

So, the cost of 1 orange is Rs 2.60.

### Step 3: Find the cost of 5 oranges
To find the cost of 5 oranges, we multiply the cost of 1 orange by 5.

\[ \text{Cost of 5 oranges} = \text{Cost of 1 orange} \times 5 = 2.60 \times 5 \]

### Step 4: Calculate the cost of 5 oranges
Now, we perform the multiplication:

\[ 2.60 \times 5 = 13.00 \]

Thus, the cost of 5 oranges is Rs 13.00.

### Final Answer
The cost of 5 oranges is Rs 13.00.
