Odpowiedź:

e) 3 3/4 - 2 2/3 + 6 - 3 5/6 = 3 9/12 - 2 8/12 + 6 - 3 10/12 = 1 1/12 + 6 - 3 10/12 =

7 1/12 - 3 10/12 = 6 13/12 - 3 10/12 = 3 3/12 = 3 1/4

f) 10 - ( 2 2/18 - 9/18 + 1 15/18 ) = 10 - ( 1 20/18 - 9/18 + 1 15/18 ) = 10 - ( 1 11/18 + 1 15/18 ) = 10 - 2 26/18 = 10 - 3 8/18 = 9 18/18 - 3 8/18 = 6 10/18 = 6 5/9

g) ( 4 5/15 - 2 6/15 ) - ( 6 9/15 - 5 10/15 ) = ( 3 20/15 - 2 6/15 ) - ( 5 24/15 - 5 10/15 ) = 1 14/15 - 14/15 = 1

h) 3 5/20 + 2 8/20 - (3 4/3 - 2 2/3 ) = 5 13/20 - 1 2/3 = 5 39/60 - 1 40/60 =

4 99/60 - 1 40/60 = 3 59/60
