Answer:
The answer is 16 ÷ 2 = 8.
Step-by-step explanation:
Now, to find the expression modeled by arrangement of tiles.
So, according to the model in the question.
There are 16 tiles in the model.
So, arrangement of 16 tiles divided into 2 groups.
Where each group consist 8 tiles.
So, we can write as:
[tex]16\div 2[/tex]
As 16 is the number of tiles and 2 is the number of groups.
Now, we can check the expression by doing the division.
[tex]16\div 2 = 8[/tex]
Therefore, each group has 8 tiles.
