    Here, we need to set up a proportion.

    40/12 = 100/x

    Cross multiply.

    40*x = 40x

    100*12 = 1200

    40x = 1200

    40x/40 = 1200/40

    x = 1200/40

    x = 30

    Final answer: It will take 30 minutes to weave 100 inches of fabric.

    I think it's 30 because you have to divide 12 by 40 and multiply the answer by 100.
