Answer 1

Bom dia!

Vamos lá.

a) 3/8 + 1/6

   9/24 + 4/24 = 13/24

b) 1/2 + 5/6

   3/6 + 5/6 = 8/6

   8/6 = 4/3

c) 1/3 + 5/6

   2/6 + 5/6 = 7/6

d) 3/4 - 1/2

   3/4 - 2/4 = 1/4

e) 5/6 - 1/3

   5/6 - 2/6 = 3/6

   3/6 = 1/2

f) 2/5 + 3/10

  4/10 + 3/10 = 7/10

g) 1/3 - 1/6

   2/6 - 1/6 = 1/6

h) 9/10 - 1/4

   18/20 - 5/20 = 13/20

i) 5/9 - 2/6

  10/18 - 6/18 = 4/18

  4/18 = 2/9

j) 11/15 - 1/2

  22/30 - 15/30 = 7/30

Espero ter ajudado!
