It can be helpful to rearrange numerators and denominators so you can see the factors cancel. The result is negative if the number of negative factors is odd. Mixed numbers are often easier to multiply if changed to improper fractions first.

  1. (5/16)(-2)(-4)(-4/5) = -(5/5·(4·4)/16·2) = -2
  2. (2/3)(-4)(9) = -(9/3·2·4) = -24
  3. (2 3/5)(7/9) = 13/5·7/9 = (13·7)/(5·9) = 91/45
  4. (-3/4)(7/8) = -(3·7)/(4·8) = -21/32
