Let +x+ = fraction of stock
neither owned by Alberto nor Renetta
+5%2F9+ = Alberto's fraction
+%285%2F9%29%2A%281%2F2%29+=+5%2F18+ = Renetta's fraction
+5%2F9+%2B+5%2F18+%2B+x+=+1+
+10%2F18+%2B+5%2F18+%2B+x+=+1+
+x+=+1+-+15%2F18+
+x+=+3%2F18+
+x+=+1%2F6+
1/6 of the stock is neither owned
by Alberto nor Renetta
