    a. 8/111 = x/5

    Solve for x.

    That is true. And funny. But my finger is 2 1/2 inches. I just need to know how to start it. Don't understand how my number are to be wrote down.

    PsyDAG set up a proportion for you to solve. Cross multiply and solve for x.

    a. 8/111 = x/5
    111x = 40
    x = 40/111
    x = ?

    12/2.5 = 0.2 feet

    Set up the proportion and solve it the same way.
