Answer 1

Resposta:

a) (+3/5) + (+1/2) = 5.2=10

b) (1/4) - (2/3) = 2.2.3=12

c) (-4/9) + (+2/3) = 3.3=9

d) (-2/5) + (1/10) - (7/10)= 5.2=10

e) (-1/8) + (-7/8) = -7

f) (3/5) - (2/3) - (1/2) = 5.2.3 = 30

g) (-1/8) + (+5/4) = 2.2.2=8

h) (1/2)-(3/4)-(4/3) =2.2.3=12

i) (-1/6) + (+2) = 2.3=6

j) (-1/7) - (2/5)= 7.5=35

k) (-4) + (-1/2)= -2

l) (+5/7) - (+2/3)= 7.3=21

m) (+0,4) + (+3/5) = 0

n) (+2/3) - (+1/2) = 3.2 =6

o) (-0,5) + (0,7)= 0

p) (-7/8)- (-3/4)= -6

q) (+1/2) + (-1/3) + (1/5) = -10

r) (-2/5) - (+1/2) =5.2=10

s) (-3/5) + (+2) + (-1/3)= 5.2.3=30

t) (+5/7) - (+1) = +7

u) (5/3) + (7/3) =3

v) (0)- (-3/7) = 0, pois todo número dividido por 0, é ele mesmo!!!

w) (1/7)+(2/7)-(17/7) = 7

x) (-4) - (-1/2) = 4

y) (-2/6) - (1/6) + (3/6) = 6

z) (+0,3)- (-1,5) = -0,5
