An apple equals 5 ounces. A plum equals 2 ounces.
weight of apples + weight of plums = total weight
? · ? + ? = ? oz

Answer 1

To find the total weight of 9 apples and 1 plum, we start by determining the weight of the apples and the plum.

1. **Weight of 1 apple**: 5 ounces.
2. **Weight of 1 plum**: 2 ounces.

Now, we can calculate:

- **Weight of 9 apples**:
\[
\text{Weight of 9 apples} = 9 \times 5 \, \text{oz} = 45 \, \text{oz}
\]

- **Weight of 1 plum**:
\[
\text{Weight of 1 plum} = 1 \times 2 \, \text{oz} = 2 \, \text{oz}
\]

Now we can find the total weight by adding the weight of the apples and the weight of the plum:

\[
\text{Total weight} = \text{Weight of 9 apples} + \text{Weight of 1 plum} = 45 \, \text{oz} + 2 \, \text{oz} = 47 \, \text{oz}
\]

Now we can write the expression based on your format:
- Weight of apples + weight of plums = total weight
- \( 9 \cdot 5 + 1 \cdot 2 = ? \, \text{oz} \)

Putting it all together:

\[
9 \cdot 5 + 1 \cdot 2 = 45 + 2 = 47 \, \text{oz}
\]

So the completed expression is:
\[
9 \cdot 5 + 1 \cdot 2 = 47 \, \text{oz}
\]

Thus, the total weight of 9 apples and 1 plum is **47 ounces**.
