Mai and her mother sent 24 invitations for her birthday party.
They put the invitation into stacks of 4.
How many stacks did they make;
We can write this as an equation;
[tex]y=\frac{x}{4}[/tex]Where, y is the number of stacks made,
and x is the number of invitations.
From here, we see that,
[tex]y=\frac{24}{4}=6[/tex]Therefore, the number of stacks they made is 6
The answer here means the number of groups.
