    Answer:

    Amy can knit \frac{1}{8} of a scarf in 1 hour.

    Step-by-step explanation:

    This question can be solved by proportions, using a rule of three.

    We have that:

    1/10 of a scarf – 4/5 of an hour

    x of a scarf – 1 hours.

    Applying cross multiplication:

    \frac{4x}{5} = \frac{1}{10}

    x = \frac{5}{10*4} = \frac{5}{40} = \frac{1}{8}

    Amy can knit \frac{1}{8} of a scarf in 1 hour.
