Answer 1

2/3 : 6/7 ; 9/14 = (2/3 x 7/6) : 9/14
                      = 14/18 : 9/14
                       = 14/18 x 14/9
                       =196/162


3 1/4 : 2 1/7 = 13/4 : 15/7
                  = 13/4 x 7/15
                  = 91/60
                  = 1 31/60

2/3 : 3 3/5 = 2/3 :18/5
                = 2/3 x 5/18
                = 10/54
                =5/27
