The watermelon is the total mass minus the mass of the papaya.<br><br>
• Watermelon = Total − Papaya<br>
• Watermelon = \(4\frac{1}{6} - 1\frac{3}{8}\)<br>
• Convert to improper fractions with common denominator 24:<br>
• \(4\frac{1}{6} = \frac{25}{6} = \frac{100}{24}\)<br>
• \(1\frac{3}{8} = \frac{11}{8} = \frac{33}{24}\)<br>
• \(\frac{100}{24} - \frac{33}{24} = \frac{67}{24} = 2\frac{19}{24}\)<br><br>
Final Answer: \(2\frac{19}{24}\) kg
