( 1/3 )( 1/21 )( )( 2/3 )

1/3 + 1/21 = 7/21 + 1/21 = 8/21

16/42 - 1/21 = 8/21 - 1/21 = 7/21 = 1/3

1/3 + 2/3 = 3/3 = 1

8/21 + 16/42 = 16/42 + 16/42 = 32/42 = 16/21

16/42 + 1 = 16/42 + 42/42 = 58/42 = 29/21

16/21 + 29/21 = 45/21 = 15/7

( 15/7)

(16/21 )(29/21 )

(8/21 )(16/42)(1 )

( 1/3 )( 1/21 )(1/3 )( 2/3 )
