Same denominators — add the whole numbers and fractions separately, then combine.<br><br>
• \(3\frac{5}{9} + 4\frac{8}{9}\)<br>
• Whole numbers: 3 + 4 = 7<br>
• Fractions: \(\frac{5}{9} + \frac{8}{9} = \frac{13}{9} = 1\frac{4}{9}\)<br>
• Total: \(7 + 1\frac{4}{9} = 8\frac{4}{9}\)<br><br>
Final Answer: \(8\frac{4}{9}\)
