1. The problem asks for an expression representing 108 divided by the sum of 2 and 7. 2. The sum of 2 and 7 is calculated as $2 + 7$. 3. The division of 108 by this sum is written as $$\frac{108}{2 + 7}$$. 4. Simplify the denominator: $$2 + 7 = 9$$. 5. Substitute back: $$\frac{108}{9}$$. 6. Perform the division: $$108 \div 9 = 12$$. 7. Therefore, the expression is $$\frac{108}{2 + 7}$$ and its value is 12.
