Excuse me, how did the answer to this math problem come from?

1= 1/2+1/3+1/6. There is already1/3 in the title, so we just need to solve1/2 and1/6.

1/2= 1/4+ 1/4

1/4= 1/5+ 1/20 ( 1)

1/4= 1/6+ 1/ 12 (2)

1/6= 1/7+ 1/42 (3)

Originally1=1/3+1/5+1/7+12+1/20+65438+.

The answer is:1/3+1/5+1/7+1/8+1/2+1/24.
