You can put this solution on YOUR website!
Think of it this way...
\n" ); document.write( "The typist is at 1/6 at time zero, and gets to 3/4 at time 6hrs.
\n" ); document.write( "The amount completed in 6 hours is:
\n" ); document.write( "\"3%2F4-1%2F6\"
\n" ); document.write( "Re-write in terms of the LCD (12)
\n" ); document.write( "\"9%2F12-2%2F12=7%2F12\"
\n" ); document.write( "So now you know that the typist can complete 7/12ths of the paper in 6 hours.
\n" ); document.write( "You need to find out how much the typist can complete in one hour. So set up
\n" ); document.write( "a proportion equation, where x is the amount completed in 1 hour:
\n" ); document.write( "\"%287%2F12%29%2F6hr=x%2F1hr\"
\n" ); document.write( "Solve for x:
\n" ); document.write( "\"x=%287%2F12%29%2F6\"
\n" ); document.write( "\"x=7%2F72\"
\n" ); document.write( "So now you have x, which is the amount of the paper that the typist can complete
\n" ); document.write( "each hour.
