Ryan can paint a fence in 10 hours, so he can paint \"1%2F10\" of the fence in one hour.
\n" ); document.write( "Assanji can paint a fence in 8 hours, so he can paint \"1%2F8\" of the fence in one hour.\r
\n" ); document.write( "\n" ); document.write( "Together they can paint \"1%2F10+%2B+1%2F8+=+4%2F40+%2B+5%2F40+=+9%2F40\" fence in an hour.\r
\n" ); document.write( "\n" ); document.write( "So it will take them \"1%2F%289%2F40%29+=+40%2F9+=+4%264%2F9\" hours, or 4 hours, 26 minutes, 40 seconds to paint the fence.
