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.
