14 20/29 - (3 13/29+2 7/29)- 5 6/7= 14 20/29- 5 20/29 - 5 6/7= 9 20/29- 5 6/7= 9 140/203 - 5 174/203= 8 343/203 - 5 174/203= 3 169/203
(5 1/14- 1 9/14)-(2 11/14+5/14)= 3 6/14 - 8 2/14 =- 7 16/14+3 6/14 = - 4 10/14= - 4 5/7
(4 13/16+8 7/16)-5 7 /16= 13 4/16 - 5 7/16= 7 13/16
15 19/32-(14 19/32+25/32)= 15 19/32-39 44/25= - 39 44/29 + 15 19/32=- 24 25/29
