  1. (q-2)/4 * -2q/(q+5)
    to multiply, we just multiply numerator by numerator and denominator by denominator. thus, this becomes:
    (q-2)(-2q) / (4)(q+5)
    observe that we can factor 2 from numerator and denominator and cancel it, and this becomes:
    -q(q-2) / (2)(q+5)

    hope this helps~ :)
