To find the number of acres in Tinyville, we can use the formula:
\[ \text{Number of acres} = \frac{\text{Total population}}{\text{Population density}} \]
Given:
- Total population = 405 Tinys
- Population density = 16.2 Tinys per acre
Now we can calculate the number of acres:
\[ \text{Number of acres} = \frac{405}{16.2} \]
Calculating this gives:
\[ \text{Number of acres} = 25 \]
Thus, the answer for Blank 1 is:
25
