Write expressions for the following using brackets. "Forty nine divided by three times the sum of five and seven".

Answer

To write the expression for "Forty nine divided by three times the sum of five and seven" using brackets, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the components of the expression**:
- We have the number 49.
- We have the number 3.
- We need to find the sum of 5 and 7.

2. **Calculate the sum of 5 and 7**:
- \( 5 + 7 = 12 \)

3. **Multiply the sum by 3**:
- Now we take the sum (which is 12) and multiply it by 3.
- \( 3 \times (5 + 7) = 3 \times 12 = 36 \)

4. **Set up the division**:
- We need to divide 49 by the result from step 3.
- This can be expressed as \( 49 \div (3 \times (5 + 7)) \).

5. **Write the final expression using brackets**:
- The complete expression is:
\[ 49 \div (3 \times (5 + 7)) \]

### Final Expression:
\[ 49 \div (3 \times (5 + 7)) \]
