Convert -60° to radians. express the answer as a multiple of p

                                                                    p
To convert degrees to radians, put degrees over 1 and multiply by ——————
                                                                   180°

 
                                            180°
To convert radians to degrees, multiply by ——————
                                             p

This problem is to convert degrees to radians, so,

                   -60°
Put -60° over 1:  ——————
                     1 

              p 
Multiply by ——————
             180°

 -60°      p
—————— · ——————
  1       180° 

Divide the -60° on top and the 
180° on the bottom both by 60°

  -1
 -60°      p
—————— · ——————
  1       180° 
           3
 
      -1p          p
     —————  or  - ———
       3           3
