How do I compute this question. I understand that its total liabilities divided by shareholders equity. I just dont understand how I get it from these numbers.

Joseph and John, Inc., had the following balance sheet results for 2006: (in millions)

Current liabilities $12.6

Bonds payable 18.6

Lease obligations 2.7

Minority interest 1.4

Common stock 8.6

Retained earnings 22.9

Compute the debt-equity ratio.
