A)
10-11,2= -1,2
-5,8-2,1= -7,9
8,1-(-3,5)= 8,1+3,5=11,6
-6,4-(-3,2)=-6,4+3,2= -3,2
7,36-8= - 0,64
b)
-6,24-5,3= -11,54
12,6-(-4,36)= 12,6+4,36=16,96
-4,23-(-6,8)= -4,23+6,8= 2,57
12-13 2/5= -1 2/5
8 2/3-(-6 2/3)=8 2/3+6 2/3=14 4/3= 15 1/3
c)
-3 5/7-6 7/8= -9 12/7 = -10 5/7
10 3/5-11 5/7= 10 21/35 -11 25/35= -1 4/35
-8 4/9-13 5/6= -8 8/18 - 13 15/18= -21 23/18= -22 5/18
-6 1/4-(-3 3/8)= -6 1/4+3 3/8= - 6 2/8+ 3 3/8= - 5 10/8 +3 3/8= -2 7/8
-7 5/6-(-10 1/7)= -7 5/6+10 1/7= -7 35/42 + 10 6/42= -7 35/42 +9 48/42= 2 13/42
