1/9!+1/10!+1/11!=122/11!
9! get cancel
= 1+ 1/10 + 1/110 = 122/110
taking L.C.M
= 110 + 11 + 1/110 = 122/110
110 get cancel
= 110 + 11 + 1 = 122
=122 = 122

to prove 1/9!+1/10!+1/11! = 122/11!
Step-by-step explanation:
1/9! +1/10×9!+1/11!
(1/9!+1/10×9!)+1/11!
taking Lcm of equation in bracket
1/9!×10/10+1/10×9!)+1/11
=11/10×9!+1/11!
11/10!+1/11×10!
taking lcm as 11
11/10!× 11/11 + 1/11!
121/11!+1/11!
