Hey friend!
(x+y)+z=x+(y+z)
(2/3 + 7/8) + -3/5 = 2/3 + (7/8 + -3/5)
(2/3*8/8 + 7/8*3/3) -3/5 = 2/3 + (7/8*5/5 - 3/5*8/8) {LCM of 8 and 3 is 24 => (16/24 + 21/24) - 3/5 = 2/3 + (35/40 - 24/40) & of 5 and 8 is 40}
=> 37/24 - 3/5 = 2/3 + 11/40
=> 37/24*5/5 - 3/5*24/24 = 2/3*40/40 + 11/40*3/3 {LCM of 24 and 5 is 120
=> 185/120 - 72/120 = 80/120 + 33/120 & of 40 and 3 is 120}
=> 117/120 = 117/120
LHS=RHS
Hence Verified
Hope it helps you!
