Simplify the left-hand side by combining the fractions with the same denominator.<br><br>
• \(\frac{9}{9} + \frac{1}{9} - \frac{2}{9} = \frac{9 + 1 - 2}{9} = \frac{8}{9}\)<br>
• The right-hand side is \(\frac{1}{9} \times \square\).<br>
• So \(\frac{8}{9} = \frac{1}{9} \times \square\).<br>
• Multiply both sides by 9: 8 = 1 &times; □ → □ = 8.<br><br>
Final Answer: 8
