Explicație pas cu pas:
[ 0, ( 3 ) + 1 , ( 3 ) : 1 7 / 9 ] : ( 1 + 1 / 12 ) =
-----------------------------------
0 , ( 3 ) = 3 / 9
1 , ( 3 ) = 1 3 / 9 = 12 / 9
-------------------------------------
[ 3 / 9 + 12 / 9 : 16 / 9 ] : ( 1 + 1 / 12 ) =
= [ 3 / 9 + 12 / 9 x 9 / 16 ] : ( 1 + 1 / 12 )
= [ 3 / 9 + 3 / 4 ] : ( 1 + 1 / 12 )
= [ 12 / 36 + 27 / 36 ] : ( 12 / 12 + 1 / 12 )
= 39 / 36 : 13 / 12
= 39 / 36 x 12 / 13
= 3 / 3
= 1
