Example Question #181 : How To Divide

\(\displaystyle 81\div9=\)

Possible Answers:

\(\displaystyle 9\)

\(\displaystyle 11\)

\(\displaystyle 8\)

\(\displaystyle 7\)

\(\displaystyle 10\)

Correct answer:

\(\displaystyle 9\)

Explanation:

When we are dividing, we are splitting things up into groups. For this problem, we can think of this as we have \(\displaystyle 81\) items and we want to split them up equally into \(\displaystyle 9\) groups. We are solving for the number of items in each group. 

We can draw \(\displaystyle 9\) circles and start putting the \(\displaystyle 81\) items, in this case triangles, into each circle equally.
