1. We want to estimate $$723 \div 9$$, and we look for numbers that are easier to compute mentally.
2. The number $$723$$ is very close to $$720$$, since:
   $$
   723 \approx 720
   $$
3. Dividing by $$9$$, the expression becomes:
   $$
   720 \div 9
   $$
4. $$720$$ is a multiple of $$9$$ (since $$9 \times 80 = 720$$), making it a compatible number for mental calculation.
5. Thus, the expression with the better compatible numbers is:
   $$
   720 \div 9
   $$
The better compatible expression is $$720 \div 9$$.
