Help for math?! How do you calculate the current ratio?

Question

Long-term assets are $800, current liabilities are $500, and long-term liabilities are $600. If the current ratio is 2.5 to 1, then current assets are?

Answer 1

If the current ration of 2.5:1 is current assets:current liabilities, then:

2.5/1 = x/500

Where x = current assets.

x = 2.5(500)

x = 1250

Answer 2

just multiply 2.5 in assets and liabilities and thats it.
