     5/ 1/3= 1/x
     5x = 1/3
       x = 1/3 /5 =1/3 x 1/5 =1/15
       x = 1/15 cup of flour to make one roll

b) 3 dozen = 36     1:1/15 and 36:x
    1/ 1/15 = 36/x
     x =36 x 1/15 = 12/5 = 2 2/5
     x = 2 2/5 cups of flour

c) 1:1/15 and x:5 2/3    5 2/3= 17/3
     1/ 1/15 = x/ 17/3
     1/15x = 17/3
         x =17/3 / 1/15
         x =17/3 x 15
         x =17 x 5
         x = 85 rolls
