The soccer field at a park is 9,000 square yards. The soccer field takes up 6 and 2/5 square inches on the map of the park. How many square yards does 1 square inch on the map represent?

To determine how many square yards 1 square inch on the map represents, we can set up the following proportion:

Let \( x \) represent the number of square yards that corresponds to 1 square inch on the map. The given information tells us that 9,000 square yards corresponds to \( 6 \frac{2}{5} \) square inches on the map.

### Step 1: Convert the mixed number to an improper fraction.
\[
6 \frac{2}{5} = \frac{6 \times 5 + 2}{5} = \frac{32}{5} \text{ square inches}
\]

### Step 2: Set up a proportion.
\[
\frac{9000 \text{ square yards}}{\frac{32}{5} \text{ square inches}} = \frac{x \text{ square yards}}{1 \text{ square inch}}
\]

### Step 3: Solve for \( x \).
To solve for \( x \), multiply both sides of the equation by 1 square inch:

\[
x = \frac{9000 \text{ square yards}}{\frac{32}{5} \text{ square inches}} = 9000 \times \frac{5}{32}
\]

Now, calculate:

\[
9000 \times \frac{5}{32} = \frac{45000}{32} = 1406.25 \text{ square yards}
\]

### Final Answer:
1 square inch on the map represents **1,406.25 square yards**.
