Hi there,
\n" ); document.write( "The ratio of natural to synthetic oil
\n" ); document.write( "= 5:3
\n" ); document.write( "If 440 liters have to be made then,
\n" ); document.write( "Add 5 + 3 = 8
\n" ); document.write( "So, 5/8 of 440 liters will be = 275 liters of natural oil
\n" ); document.write( "and, 3/8 of 440 liters will be = 165 liters of synthetic oil
\n" ); document.write( "Hope this helps :-)
\n" ); document.write( "
