Answer 1

a)-4 1/2 + 1/6 + (-1/2) + 11/3=-4 3/6 + 1/6 +(-3/6) + 22/6=3 27/6 =7 3/6 = 7 1/2

b) 6,25 + (-1/4) + (-3/5) + 0,75= 1/4 +(-1/4) + (-3/5) + 3/4 = 5/20 +(-5/20) + (-12/20) + 15/20 = (-2/20)

c) 4/7 + (-3/14) + 1/14 = 8/14 + (-3/14) + 1/14 = 6/14 = 3/7

d) 1/2 + (-3/4) + (-5/8) = 4/8 + (-6/8) + (-5/8) = 3/8

e) 52/3 + (-34/5) + 1/3 + (-1/5) = 260/15 +(-102/15) + 5/15 + (-3/15) = 160/15 = 10 10/15

f) 16 4/5 + (-4,8) + 3 1/5 + (-4 1/5) = 16,8 + (-4,8) + 3,2 + (-4,2) = 11
