Answer :
1.41
The quick ratio is the sum of assets that can be quickly liquidated divided by the liabilities. In this case, the assets are the cash of $316 and the accounts payable of $709. The inventory doesn't count since it can't be quickly converted to liquid assets. The liabilities are the accounts payable of $709. So let's do the math.
(316 + 687)/709 = 1003/709 = 1.41
So the result is 1.41
