Question

calcule as frações e se possivel simplifique o resultado:
a)1/10 + 7/10=
b)5/6- 1/6=
c)1/10 + 7/10 - 3/10=
d)7/15- 3/15 - 1/15=
e)7/20 + 1/20 + 7/20=
f)5/18 + 11/18 - 13/18=
g)7/6 + 4/6 - 5/6 + 3/6 - 9/6=
h)1/20 + 3/20 + 11/20 - 7/20 =
​

Answer 1

Resposta:

a) 1/10 + 7/10 = 8/10 : 2 = 4/5

b) 5/6 - 1/6 = 4/6 : 2 = 2/3

c) 1/10 + 7/10 - 3/10 = 5/10 : 5 = 1/2

d) 7/15 - 3/15 - 1/15 = 3/15 : 3 = 1/5

e) 7/20 + 1/20 + 7/20 = 15/20 : 5 = 3/4

f) 5/18 + 11/18 - 13/18 = 3/18 : 3 = 1/6

g) 7/6 + 4/6 - 5/6 + 3/6 - 9/6 = 0/6 = 0

h) 1/20 + 3/20 + 11/20 - 7/20 = 8/20 : 4 = 2/5
