Hi,

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

I hope this helps you.
