To solve the problem, let's assume the common setup where we have the following equations:

Given:

1. (a + \frac{1}{b} = 1)
2. (b + \frac{1}{c} = 1)

Find: (c + \frac{1}{a})

Step 1: Express (a) in terms of (b)
From equation 1:
(a = 1 - \frac{1}{b} = \frac{b - 1}{b})
Thus, (\frac{1}{a} = \frac{b}{b - 1})

Step 2: Express (c) in terms of (b)
From equation 2:
(\frac{1}{c} = 1 - b)
Thus, (c = \frac{1}{1 - b} = -\frac{1}{b - 1})

Step 3: Calculate (c + \frac{1}{a})
(c + \frac{1}{a} = -\frac{1}{b - 1} + \frac{b}{b - 1} = \frac{b - 1}{b - 1} = 1)

Answer: (\boxed{1})
