Answer 1

a) -7/2+11/2 = -7+11/2 = 4/2 = 2

b) -10/3 - (-13/3) = -10/3 + 13/3 = -10+13/3 = 3/3 = 1

c) -2/5 + (-7/2) = -2/5 - 7/2 = -4-35/10 = -39/10 = -3,9

d) -5/9 - (-4/3) = -5/9 + 4/3 = -5+12/9 = 7/9 = 0,78

e) -4/3 - 9/4 = -16-27/12 = -43/12 = -3,58

f) -3/2 -1/3 - 2/5 = -45-10-12/30 = -67/30 = -2,23
