Define the variables for the situation. Then enter an equation. The pencils were divided into 8 groups of 2.
p = (select)
Enter an equation:
=
8

p = 16/8 = 2

Step-by-step explanation:

We know that the pencils were divided into 8 groups of 2.

Then the total number of pencils is equal to 8  (the number of groups) times 2 (the number of pencils in each group)

8*2 = 16

The total number of pencils is 16.

Then the operation of dividing 16 pencils into 8 groups is written as:

16/8

And we know that this is equal to 2, then the operation is:

16/8 = 2.

Then the equation is:

p = 16/8 = 2

where p represents the number of pencils in each group.
