Analyzing Ratios (Answer all please!)

NOTE : I posted a previous question and that was not answered completely can someone please finish the question properly? thank you. I paid extra.

One of the most important applications of ratio analysis is to compare a company's performance with that of other players in the industry or to compare its own performance over a period of time. Such analyses are referred to as comparative and trend analysis, respectively. Common size analysis requires the representation of financial statements in relation to a single financial statement item or base. What is the most commonly used base item for a common size balance sheet in the analysis? Earnings before interest and taxes Net sales Total assets Net income Suppose you are conducting an analysis of Curr Manufacturing Co.'s past three years' performance. The company did not issue new shares in these three years and has faced some operational difficulties. The company has thus piloted some new forecasting strategies for better operations management. You have collected relevant data, made reasonable assumptions based on the information available, and calculated the following ratios. Based on the preceding information, your calculations, and your assumptions, which of the following statements can be included in your analysis report? Check all that apply. The company's creditworthiness has improved over these three years as evidenced by the increase in its debt-to-equity ratio over time. Curr Manufacturing Co.'s ability to meet its debt obligations has worsened since its debt-to-equity ratio increased from 0.60 to 0.77. A plausible reason why Curr Manufacturing Co.'s price-to-cash-flow ratio has increased is that investors expect higher cash flow per share in the future. The market value of Curr Manufacturing Co.'s common shares declined over the three years
