Answer 1

To find out how many dozens of eggs you can purchase with 9 cowry shells, you can set up the relationship based on the information given.

1. A dozen eggs costs 2 cowry shells.
2. You have 9 cowry shells.

Now, divide the total number of cowry shells you have by the cost of one dozen eggs:

\[ \text{Number of dozens} = \frac{9 \text{ cowry shells}}{2 \text{ cowry shells/dozen}} = 4.5 \text{ dozens} \]

Since you cannot purchase a fraction of a dozen, you round down to the nearest whole number. Therefore, you can purchase 4 dozens of eggs.

So the answer is:

4 dozen
