Add their rates of mowing
\n" ); document.write( "( 1 lawn / 3 hrs ) + ( 1 lawn / 5 hrs ) = ( 1 lawn / t hrs )
\n" ); document.write( " $\"+1%2F3+%2B+1%2F5+=+1%2Ft+\"$
\n" ); document.write( "Multiply both sides by $\"+15t+\"$
\n" ); document.write( " $\"+5t+%2B+3t+=+15+\"$
\n" ); document.write( " $\"+8t+=+15+\"$
\n" ); document.write( " $\"+t+=+1.875+\"$
\n" ); document.write( "It will take them 1.875 hrs \n" ); document.write( "
