________☺️________
x = 3/4
y=2/5
z= -5/7
To Verify:-
x+(y+z)=(x+y)+z
3/4+[2/5+(-5/7)]= (3/4+2/5)+(-5/7)
3/4+[2×7+(-5×5)/35]= (3×5+2×4/20)-5/7
3/4 + [14+(-25)/35]= (15+8/20)-5/7
3/4 + (14-25/35)= 23/20-5/7
3/4+(-11/35)=23×7+(-5×20)/140
3/4-11/35 = 161+(-100)/140
3×35-11×4/140 = 61/140
105-44/140 = 61/140
61/140 = 61/140
Hence verified ✔️✔️
