Step-by-step explanation:
Required
Interpret the division model
A division model is of the form: Dividend ÷ Divisor
In the attached figure (in the question), there are 5 vertical partitions.
This vertical partitions represents the result of the model
Also from the question attachment;
The horizontal partitions on the left, if traced to the right side of the diagram means that each vertical partition is divided into 3 and this represents the divisor of the model.
So, we have:
To get the quotient of the model, I'll make use of my attached file.
Counting the number of boxes, we can see that there are 15 boxes in total.
So, we have:
<em>Hence, the division model is: 15 ÷ 3</em>
