A) (-5) - (-1 3/4)= - 5 -1 3/4= -5 3/4
b) (-2,2) + (-10 1/5)= -2,2 - 10 1/5= -2 1/5 -10 1/5= -12 2/5
c) -(-1 1/3) + (-15)= 1 1/3-15= 1 1/3 - 14 3/3= -13 2/3
d) -(-9) - (-4 1/4)= 9 + 4 1/4= 13 1/4
e) (-3 2/5) - 4,8= - 3 2/5 - 4 4/5= - 7 6/5= -8 1/5
4 8/10= 4 4/5
f) 2 1/3 + (-5 3/5)= 2 1/3 - 5 3/5=2 5/15 - 5 9/15=
= 1 20/15 - 5 9/15= - 5 11/15
