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.
