How do you calculate ratios on an annual statement and show if there is an increase or loss?

I need to find the following on this annual report from Lowes Financial ratios (at least one profitability, leverage, liquidity, and efficiency) o At least one efficiency ratio to support whether the organization is running efficiently o At least one profitability ratio to support how profitable the organization is o At least one leverage ratio to support whether the company is sustainable o At least one liquidity ratio to support whether the company is able to pay its bills )
