Identify the given values and operation

\[

$$\begin{aligned} &\text{Melon weight} = 5.988\text{ pounds}\\ &\text{Cherries weight} = 3.902\text{ pounds}\\ &\text{Operation} = \text{Addition (total weight)} \end{aligned}$$

\]

Calculate the sum of the decimals

\[

$$\begin{aligned} 5.988 + 3.902 &= 5.988 + 3.000 + 0.902 \\ &= 8.988 + 0.902 \\ &= 9.890 \\ &= 9.89 \end{aligned}$$
