Final answer:
The algebraic expression for the word problem '8 divided into x groups' is 8 / x.
Step-by-step explanation:
The correct choice is 1) 8 / x.
In the word problem, 8 is being divided into x groups. This means we need to divide 8 by x to determine the size of each group. The expression 8 / x represents this division.
For example, if x is equal to 4, then 8 divided into 4 groups would be 8 / 4 = 2, meaning each group would have a size of 2.
