20/9=1/( )+1/( )
17/72=1/( )+1/( )
23/132=1/( )+1/( )
1/42=1/( )+1/( )
1/132=1/( )+1/( )
2/35=1/( )+1/( )
17/72=1/( )+1/( )
23/132=1/( )+1/( )
1/42=1/( )+1/( )
1/132=1/( )+1/( )
2/35=1/( )+1/( )
9/20=1/4+1/5
17/72=1/8+1/9
23/132=1/11+1/12
1/42=1/63+1/126
1/132=1/198+1/396
2/35=1/21+1/105
这题是无法解的, 因为20/9就不是两个真分数的和!
20/9=1/(9/17)+1/(3)
17/72=1/(8)+1/(9)
23/132=1/(11)+1/(12)
1/42=1/(6)+1/(-7)
1/132=1/(11)+1/(-12)
2/35=1/(5)+1/(-7)
20/9=1/( )+1/( )
写倒了吧
9/20=1/4+1/5
17/72=1/(8 )+1/(9 )
23/132=1/( 11 )+1/( 12 )
1/42=1/( 63 )+1/( 126 )
1/132=1/( 198 )+1/( 396 )
2/35=1/( 20 )+1/( 140 )
17/72=1/(8)+1/(9)
