    DIY question:
    Let e be the identity element
    a*e = e*a = a
    a*e= 3ae/7 =a
    Both the a cancel out
    3e/7=1
    Therefore e= 7/3
    Ans.

    a*e=e*a=a
    3ae/7=a
    hence, e=7/3
    Also, e*a=a
    3ea/7=a
    7a=7a
    hence, a=a
    So, identity element in for * is 7/3

    Mam I have a doubt
    In the 4th sum we are taking e=1
    Can we think of 'e' as a factor of 'a'
    Such that LCM(a,e) =a
    Where 'e' is a factor of 'a'
