    Answer:

    45

    Step-by-step explanation:

    In questions such as these it is implied Anita can and does work at a constant rate. Therefore, we can set up the following proportion:

    \frac{25}{5.5}=\frac{x}{9.9}, where x represents the number of wooden slats she can paint in 9.9 hours.

    Multiplying both sides by 9, we get:

    x=\frac{9.9\cdot 25}{5.5},\\x=\boxed{45}

    Hello!

    25 wooden ….. 5.5 hours

    x wooden ….. 9.9 hours

    _____________________

    25/x = 5.5/9.9

    25 × 9.9 = x × 5.5

    247.5 = x × 5.5

    x × 5.5 = 247.5

    x = 247.5 : 5.5

    x = 45 wooden

    Good luck! 🙂
