To find the missing value in the proportion, we can set up a ratio based on the information given.
We know that:
1 inch is to 9 miles as \( x \) inches is to 81 miles.
This can be set up as the proportion:
\[
\frac{1 \text{ inch}}{9 \text{ miles}} = \frac{x \text{ inches}}{81 \text{ miles}}
\]
To solve for \( x \), we can cross-multiply:
\[
1 \times 81 = 9 \times x
\]
\[
81 = 9x
\]
Next, divide both sides by 9:
\[
x = \frac{81}{9} = 9
\]
Thus, \( x \) is 9 inches.
So, we have:
1 inch is to 9 miles as 9 inches is to 81 miles.
