    Given problem is,


    3/5 + 7/3 + ( – 2/ 5 ) + ( – 2 / 3 )


    = 3 / 5 + ( – 2 / 5 ) + 7 /3 + ( – 2 / 3 )


    [ rearranged the like fractions at one place ]


    = 3 / 5 – 2 / 5 + 7 / 3 – 2 / 3 [ since + × – = – ]


    = ( 3 – 2 ) / 5 + ( 7 – 2 ) /3


    = 1 / 5 + 5 / 3


    LCM of 5 and 3 = 5 × 3 = 15


    = ( 3 + 25 ) / 15


    = 28 / 15

    Hope this helps!
