Explicação passo a passo:

a) 3/7 + 2/14 =

Igualando os denominadores:

6/14 + 2/14 =

8/14 = 4/7.

b) 8/8 + 4/6 =

Igualando os denominadores:

24/24 + 16/24 =

40/24 = 5/8.

c) 4/12 + 2/8 - 3/6 =

Igualando os denominadores:

8/24 + 6/24 - 12/24 =

14/24 - 12/24 =

2/24 = 1/12.

d)3/4 + 2/12 + 5/16​ =

Igualando os denominadores:

36/48 + 8/48 + 15/48 =

44/48 + 15/48 =

59/48.
