Answer:
3
pastries
Explanation:
Amount to be shared / number of people sharing
23 / 7
To simplify easily in our heads, we can take 23 and subtract 7. That then becomes a 1. Subtract 7 again, it becomes a 2. We can do this until we have taken all of the wholes (equivalent to 1) out of 23/7. The math for this is shown below.

Have a nice day!
