First you need to know what \(34 1/4\) is in a decimal. It will equal \(34.25\).
Then you need to know how many liters equal a millimeter. \(0.001\) liters equal a millimeter, or in other words \(1,000\) millimeters equals a liter.
Next you multiply, which you should know if that is \(1,000\) then you just fill the multiplication problem with \(0\). As in this equation if you multiply \(34\) to \(1,000\), you'll get \(34,000\). So if you do \(34.24\)... it will change into \(34,250\). If it was in a cubic way it would be \(34,250,000\). So the answer is \(34,250\), or \(34,250,000\). But we're not finished until were done subtracting to get out answer.
\(40\) liters equals \(40,000\) millimeters, \(40,000\) - \(34,250\)... which is \(5,750\).
