a)- 5 1/6 + ( - ½) + 5,5 = - 5 4/6 + 5,5 = - 5 4/6 + 5 3/6 = - 1/6
c) - ( 4 7/8 + 0,125) - [- (0.9)] = -5 - 9 = -4
d) 0.25 + ( - 1/4) - (-3 3/8 ) = - 1,15 + 3 3/8 = 2,3
zaraz dodam restzę, bo się boję, ze mi zabiora te dwa pkt ;)
e) - 2,1 - (-8 1/3+ 11 2/3 ) = - 2,1 - 3 1/3 = - 2,1 + ( - 3 1/3 ) = -2 1/10 + ( - 3 1/3 ) = -2 3/30 + ( - 3 10/30) = -5 13/30
f) 1.25 + ( -2 7/12 ) = 1 1/4 + ( - 2 7/12 ) = 1 3/12 + ( - 2 7/12 ) = - 1 4/12 = -1 1/3
g) - ( -8,8) - 5 1/6 = 8,8 - 5 1/6 = 8 8/10 - 5 1/6 = 8 4/5 - 5 1/6 = 8 24/30 - 5 6/30 = 3 18/30 = 3 9/15
c) - ( 4 7/8 + 0,125) - [- (0.9)] = -5 - 9 = -4
