5 : 7    means that there are 12 equal parts  of the $240

 

And Kate gets 7  of these....so......

 

(7/12) * $240   =   7 * $20   =  $140

 

And Janee has $100

If they each spend  $20   there is  $200  left

 

Jane has $80    and Kate has  $120

 

So

 

80  :  120   =

 

8   :  12   =

 

2  :  3

 

 

cool cool cool
