$\"1.8=9%2F5\"$
\n" ); document.write( "The multiplicative inverse is $\"1%2F%28%289%2F5%29%29=1%285%2F9%29=5%2F9\"$
\n" ); document.write( "There is no way to write that as an exact decimal.
\n" ); document.write( "
\n" ); document.write( "If you are trying to convert degrees Farenheit to Celsius, you can easily use the fraction.
\n" ); document.write( "The scales meet at $\"-40%5Eo\"$ and you can use other reference points like the freezing point of water, which is $\"32%5Eo\"$ $\"F\"$ anf $\"0%5Eo\"$ $\"C\"$
\n" ); document.write( "
\n" ); document.write( "If yout temperature is $\"104%5Eo\"$ $\"F\"$ , that is
\n" ); document.write( " $\"104%5Eo\"$ $\"F-32%5Eo\"$ $\"F=72%5Eo\"$ $\"F\"$ above freezing
\n" ); document.write( "To get to degrees Celsius multiply times $\"5%2F9\"$ which means multiply times 5 and divide by 9, or divide by 9 first and then multiply times 5.
\n" ); document.write( "Either way $\"72%2A%285%2F9%29=40\"$ , so $\"104%5Eo\"$ $\"F=40%5Eo\"$ $\"C\"$
\n" ); document.write( " \n" ); document.write( "

\n" );
