1.  (7 + 1/4) (4)   =   29

(5  + 1/2) (4)  =   22

The first  train had 7 more  riders  than the 3rd

2.   3/4  of  a row  was empty.......(3/4) (4)  = 3  more riders needed  to completely fill the train

3.    8 - ( 5 + 1/2)  = 8 - ( 11/2)  =  (16/2)  - (11/2)   =  5/2  =  2 1/2  rows were empty

(5/2) (4)  =  20 / 2  = 10 more  rideres needed  to completely fill the train
