the mogul runners ski club planned a trip to park city. of the total number of club members, 11 signed up to go. if this is 55% of the club, how many members does the ski club have?

11 souls  =  55% of the club

' 55% ' means 0.55 .
' of ' means ' times '.

                                      11 souls  =  0.55 x Club

Divide each side by  0.55 :  Club  =  11/0.55  =  20 souls
