Let’s go step-by-step.

**1. Calculate Funds from Operations (FFO)**  
FFO is generally:  
\[
\text{FFO} = \text{Profit Loss from Operating Activities} + \text{Depreciation, Amortization, Provisions, and Impairment} - \text{Income Tax Paid} - \text{Interest Paid} + \text{Interest Received} + \text{Dividends Received}
\]  

From the data (2022):
- Profit Loss from Operating Activities = 1,334,000,000  
- Dotacion Amortizacion Y Variacion De Provisiones = 762,000,000  
- Impairment Loss Reversal = –15,000,000 (adds back if negative? Already included in operating profit, so we use the amortization line which includes provisions)  
- Income Tax Paid = 215,000,000  
- Interest Paid = 209,000,000  
- Interest Received = 40,000,000  
- Dividends Received = 89,000,000  

So:
\[
\text{FFO} = 1,334M + 762M - 215M - 209M + 40M + 89M = 1,801,000,000
\]

**2. Calculate Net Debt**  
Net Debt = Noncurrent Borrowings + Current Borrowings – Cash and Equivalents

Noncurrent borrowings:  
- Participaciones Preferentes Obligaciones Y Otros Valores Negociables No Corrientes = 3,101,000,000  
- Noncurrent Loans = 2,624,000,000  
- Noncurrent Lease Liabilities = 439,000,000  
Sum = 6,164,000,000

Current borrowings:  
- Participaciones Preferentes Obligaciones Y Otros Valores Negociables Corrientes = 1,139,000,000  
- Current Loans = 553,000,000  
- Current Lease Liabilities = 72,000,000  
Sum = 1,764,000,000

Total Debt = 6,164M + 1,764M = 7,928,000,000  
Cash and Cash Equivalents = 2,360,000,000  
Net Debt = 7,928M – 2,360M = 5,568,000,000

**3. Ratio**  
\[
\frac{1,801,000,000}{5,568,000,000} \approx 0.32346
\]

**Final value:**
