Answer 1

A) -7 4/9- 2 1/6 = -7 8/18 - 2 3/18 = -9 11/18
b) 3 1/4 - 8 5/6 = 3 3/12 - 8 10/12 = - 5 7/12
c) -2 3/5 + 7 1/3 = -2 9/15 + 7 5/15 = 4 11/15
d) - 3,12 - 6,1 = - 9,22
e) -7,2+ 12,36 = 5,16
f) 6,4-10,25 = - 3,85
g) -3 1/7 - 1,2 = -3 1/7 - 1 2/10 = -3 10/70 - 1 14/70 = -4 24/70 = -4 12/35
h) 4 5/6 - 8,2 = 4 5/6 - 8 2/10 = 4 25/30 - 8 6/30 = -3 11/30

a) -5,65+(-2,08)- 1,35 = -7,73 - 1,35 = -9,08
b) 6,510+ (-2,775)-11,125 = 3,735 - 11,125 = -7,39
c) -10/9+(1/6) + 9 3/4 - ( -6,25)= nie wiem :c
d) -9,3-(-12 1/5)- (72,8-(-13,002))= -9,3 - (-12,2) - 85,802 = 2,9 - 85,802 = - 82,902

Answer 2

A) = -7 10/54 - 2 10/54 = -9 20/54
b)=3 7/24 - 8 9/24= - 5 2/24 = -5 1/12
c)= -2 6/15 + 7 6/15= 5 12/15
d)=-9,22
e)=5,16
f)-3,85
g)=- 3 1/7 - 1 2/10 =-3 11/70 - 1 9/70 = -4 20/70= -4 2/7
h)=4 5/6 - 8 2/10= 4 5/60 - 8 8/60 = -4 3/60 = -4 1/20

Zadanie 2
a) -5,65+ (-2,08)- 1,35=- 5,65 -2,08-1,35=-9,08
b) 6,51+ (-2,775)-11,125=6,51-2,775-11,125=-7,39.
