Profitability Ratio

I need the profitability ratio for the following:

1) Interest expense

2) Income taxes

3) Net income

I was using the formula of Interest expense EBIT divided by Interest expense but this does not seem correct.

Please explain the formulas to use to achieve the % ratio for these 3 items.

Please provide the profitability ratios for interest expense, income taxes and net income. I have already complete the profitability ratio for COGS, Gross profit/Gross margin, Sell & Admin & depreciation and Operating profit (EBIT)
