2.) Wykonaj działania:
a) 3 1/4 - 5 1/6 + 7/12 = 3 3/12 - 5 2/12 + 7/12 = -1 11/12 + 7/12 = - 1 4/12 = -1 1/3
b) 1 3/4 + 5/6 = 1 9/12 + 10/12 = 1 19/12 = 2 7/12
c) [1 1/3 - 2 1/2] - [3 1/4 - 4 1/2] = [8/6 - 15/6] - [13/4 - 18/4] = - 7/6 + 5/4 = - 14/12 + 15/12 = 1/12
d) 1/12 - 1/6 - 1/3 = 1/12 - 2/12 - 4/12 = - 5/12
e) 1,5 - 3 4/7 = 1 1/2 - 3 4/7 = 3/2 - 24/7 = 21/14 - 48/14 = - 27/14 = - 1 13/14
a) 4/5 < 7/8

a) 13/4 - 31/6 + 7/12 = 39/12 - 62/12 + 7/12 = -23/12 + 7/12 = -16/12 = -4/3 = -1 1/3
b) 7/4 + 5/6 = 14/12 + 10/12 = 24/12 = 2
c) (4/3 - 5/2) - (13/4 - 9/2) = (8/6 - 15/6) - (13/4 - 18/4) = -7/8 - (-5/4) = -7/8 + 10/8 = 3/8
d) 1/12 - 2/12 - 4/12 = -1/12 - 4/12 = -5/12
e) 3/2 - 24/7 = 21/14 - 48/14 = -27/14 = -1 13/14
