- The ratio of black to white tablet covers is 5:9.

- There are 450 white tablet covers.

- Use the ratio to determine the number of black covers.

- Set up a proportion: \(\frac{5}{9} = \frac{x}{450}\).

- Solve for \(x\), where \(x\) is the number of black covers.

- Cross-multiply to get: \(9x = 5 \times 450\).

- Simplify: \(9x = 2250\).

- Divide both sides by 9: \(x = 250\).

- Option 4: 250 is correct.
