To estimate the sum of \( 28 + \frac{10}{27} \), you can break the process into two steps:

1. **Estimate the fraction** \( \frac{10}{27} \):  
   Since \( 10 \div 27 \approx 0.37 \), the fraction can be approximated as 0.37.

2. **Add the values**:  
   \( 28 + 0.37 = 28.37 \).

So, the estimated sum is **28.37**.
