Find the unit rate.

Question

78 plates in 6 stacks =
plates per stack

Answer 1

To find the unit rate, you divide the total number of plates by the number of stacks.

So, you divide 78 plates by 6 stacks:

\[ \frac{78 \text{ plates}}{6 \text{ stacks}} = 13 \text{ plates per stack} \]

Therefore, there are 13 plates per stack.
