I have inventory of 840,000 total assets 2,800,000 current ratio 2.25 acid test ratio 1.2 debt to equity ratio 1.8

I need to find out how to calculate current assets( is it 2800000?), shareholders equity , long-term assets and long-term liabilities from above info. I know how to do ratios but do I go backwards to find this info the book doesn't explain this, a little lost.
