first find the sum of -8/7 and -5/3 :
lcm = 21
= -24/21 and 35/21
(-24 + 35) /21
=59/21
now sum of 3/2&-31/28
LCM = 28
= 42/28 & -31/28
[42+(-31) ] /28
=11/28
Now subtract the sums :
59/21 - 11/28
LCM = 84
= 236/84 -33/84
=225/84
lcm = 21
= -24/21 and 35/21
(-24 + 35) /21
=59/21
now sum of 3/2&-31/28
LCM = 28
= 42/28 & -31/28
[42+(-31) ] /28
=11/28
Now subtract the sums :
59/21 - 11/28
LCM = 84
= 236/84 -33/84
=225/84
