							Dear student

k1 = 1
k2 = 2
k3 = 3
in series
k (eq)_ = 1/k1+1/k2+1/k3
= 1/1+1/2+1/3 = 11/6
so, final answer will be 6/11

the same formula will going to be used in this case also . 
k1 = 1 
k2 = 2 
k3 = 3
in series 
k (eq)_ = 1/k1+1/k2+1/k3 
= 1/1+1/2+1/3 = 11/6 
so, final answer will be 6/11 
beacuse 1/ k (eq ) = 11/6
