Multiply the mass of one basketball by 2 to get the mass of 2 similar basketballs.<br><br>
• Mass of 2 basketballs = \(2 \times 1\frac{5}{6}\)<br>
• Convert the mixed number: \(1\frac{5}{6} = \frac{11}{6}\)<br>
• \(2 \times \frac{11}{6} = \frac{22}{6}\)<br>
• Simplify: \(\frac{22}{6} = \frac{11}{3} = 3\frac{2}{3}\)<br><br>
Final Answer: \(3\frac{2}{3}\) kg
