Step-by-step explanation:
(b+c) =4/9+( -5/6 )
Take lcm of 9 and 6
which is 18
(b+c) =(8-15)/18
= (-7/18)
similarly,
(a+b) = 2/3+4/9
Take lcm of 3 and 9
which is 9
(a+b) =(6+4)/9
= 10/9
To prove , a+( b+c) = (a+b)+c
2/3 + (-7/18) = 10/9+(-5/6)
Take lcm of 3 and 18 which is 18
and also take lcm of 9 and 6 which is 18
(12-7)/18 = (20-15)/18
5/18 = 5/18
L.H.S = R.H.S
Hence,proved
