Evaluate using BODMAS:
`(9+4-5)-:(16+8-20)`

Answer

To evaluate the expression `(9 + 4 - 5) ÷ (16 + 8 - 20)` using BODMAS, we follow these steps:

### Step-by-Step Solution:

1. **Identify the expression**:
We have `(9 + 4 - 5) ÷ (16 + 8 - 20)`.

2. **Solve the brackets first**:
- For the first bracket:
\[ 9 + 4 - 5 \]
- First, add:
\[ 9 + 4 = 13 \]
- Then subtract:
\[ 13 - 5 = 8 \]

- For the second bracket:
\[ 16 + 8 - 20 \]
- First, add:
\[ 16 + 8 = 24 \]
- Then subtract:
\[ 24 - 20 = 4 \]

3. **Rewrite the expression with the results from the brackets**:
Now we have:
\[ 8 ÷ 4 \]

4. **Perform the division**:
\[ 8 ÷ 4 = 2 \]

5. **Final Answer**:
The final answer is **2**.
