\n" ); document.write( "QUESTION: If you mixed 20 litres of 2 stroke fuel with 20 litres of 4 stroke fuel, what would be the ratio of unleaded petrol to oil in the combined mix?--------------------
\n" ); document.write( "Equation:
\n" ); document.write( "oil + oil = oil
\n" ); document.write( "20*1 + 20*2 = 60 litres of oil
\n" ); document.write( "---
\n" ); document.write( "petrol + petrol = petrol
\n" ); document.write( "20*19 + 20*18 = 740 litres of petrol
\n" ); document.write( "-----
\n" ); document.write( "Answer:: 740:60 = 74:6 = 37:3
