Find P if R= 66 2/3% and B=120

Question

Need help with this equation.  I cannot understand how to calculate this.  

Answer 1

The basic percent formula is P = r  

                                               B   100

 

P   = 66 2/3

120    100

 

100P = 120(66 2/3)

100P = 120(200)

                     3

100P = 8000

     P = 80
