tutorsd6 : yes
student : can you help me with this problem
tutorsd6 : multiply each term with 75
student : ok
tutorsd6 : 75 ( r/15 ) - 75 ( r / 25 ) = 75 ( 1/15 )
tutorsd6 : 5r - 3r = 5
student : how did you get 75??
tutorsd6 : 2r = 5 = > r = 5/2 = 2.5 ( answer )
student : is that the common denominater??
student : I don't understand stil
student : sorry understand the 75 part but how did you get 2r=5 = >r = 5/2 = 2.5
tutorsd6 :
75 ( r/15 ) = 5r ( 75/15 = 5 )
tutorsd6 : 75 ( r / 25 ) = 3r [ 75/25 = 3 ]
tutorsd6 : right side : 75 ( 1/15 ) = 75 / 15 = 5
student : ok
tutorsd6 : left side : 5r - 3r = 5 ( right side )
tutorsd6 : 2r = 5
tutorsd6 : r = 5/2 = 2.5
student : oh ok
