Answer 1

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.
