To find out how many grapes Rob has, we know that Fiona has 7 grapes and that she has 3 fewer grapes than Rob.
We can set up the equation like this:
Let \( R \) be the number of grapes Rob has.
According to the information given:
\[ R = 7 + 3 \]
\[ R = 10 \]
So, Rob has 10 grapes.
Now regarding the bar model: The top bar (question mark) represents the total number of grapes Rob has, and the lower bar is divided into two sections: one part labeled 10 and one part labeled 3. The part labeled 10 represents Rob's grapes, while the part labeled 3 represents the difference between Rob's and Fiona's grapes.
Since Rob has 10 grapes, the missing number in the model is:
**10**.
