b) 1 5/6 - 3 1/3 = 1 5/6 - 3 2/6 =11/6- 20/6 =-9/6 = -1,5
c) 4,3 - 7,5 = -3,2
d) -4,5 - 2,1/4 = -4,50 - 2,25 = -6,75
e) -3 1/6 -(- 5 5/6) = -3 1/6 + 5 5/6= -`19/6 + 35/6 = 16/6 = 2 4/6 = 2 2/3
r) 7 1/3 -(- 4 5/6)= 7 2/6 + 4 5/6 =12 1/6
g) -5 4/7 + 7= -32/7 +49/7 = 17/7 = 2 3/7
h) 1,23 - 9= - 7,77
i) -6 -(-4 4/5)= -6+ 4 4/5 -30/5 +24/5 = -6/5 = -1 1/5
