Evaluate:
1/3+1/15+1/35+1/63+1/99+1/143
1/3 = 5/15
= 5/15+1/15+1/35+1/63+1/99+1/143
= 6/15+1/35+1/63+1/99+1/143
= 2/5+1/35+1/63+1/99+1/143
2/5 = 14/35
= 15/35+1/63+1/99+1/143
= 3/7 + 1/63+1/99+1/143
3/7 = 27/63
= 28/63+1/99+1/143
= 4/9+1/99+1/143
= 45/99+1/143
= 5/11 + 1/143
= 65/143 + 1/143 = 66/143
= 6/13</PRE>
