50:1 ---> 50x L of gas, 1x L of oil\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "50x + 1x = 20\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "51x = 20\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "x = 20/51\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "-------------------------------------------------------\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "so you should mix 20/51 Liters of oil\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "20/51 is approximately 0.39215686\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "so you should have approximately 0.39215686 liters of oil\r
\n" ); document.write( "\n" ); document.write( "------------------------------------------------------------------------------------------------------------------------\r
