  1. Your first two equations are both wrong.

    128/800 = 0.16 = 16%

  2. I'd set it up with %/100=part/whole, then multiply top to bottom across the equal sign and divide by the other number.
    Your 625 answer doesn't make sense, due to the fact that they want the percentage... if it doesn't make sense, it can't be right:)

  3. <BSV=<ABS
    Angle y is the sum of <asw and <wsc.
