There are 5 sandwiches and 10 students.
Each student would have to share the sandwich.
How many pieces will they be divided into?
If we divide each sandwich into 2 pieces then there will be 10 pieces.
[tex]2\times5=10\: \text{pieces}[/tex]Since there are 10 students so each student will get one piece of sandwich.
Therefore, we need to divide each sandwich into 2 pieces so that the total number of pieces are 10.
