Question 1- current ratio

I thought it was 1:1 because the formula is current assets / current liabilites but this is wrong.shouldn't I be using the total of assets and liabilities? What am I doing wrong?

Question 2- cash debt coverage
I know the formula is cash provided by operations / average total liabilities. So I took 48,000/ 335,000 but this is wrong. (350K 320K)/2=335,000

Question 3 current cash debt coverage
I know the formula is cash provided by operations / average current liability so I took 48,000/87,500. 87,500 is the average of all the liabilties number on the 2010 column but this is incorrect.

I know the formulas, but I don't know what numbers to plug in to get the correct answer for these last 3 questions. I figured out all the other questions.

Thank you
