\n" ); document.write( "A typical shared work equation
\n" ); document.write( "(each will do a fraction of the work; the two fractions add up to 1)
\n" ); document.write( "\"11%2F20\" + \"11%2Fr\" = 1
\n" ); document.write( "Multiply equation by 20r, results
\n" ); document.write( "11r + 20(11) = 20r
