me ajudem pf.

Answer 1

someem cimae some em baixo.. 1/2 + 2/3= 3/5
no caso negativo subtraia.. 5/4-1/2 = 4/2 =2

quando der simplifique!

Answer 2

1/2 +2/3 =
3/6 + 4/6
7/6

5/6+2/3=
5/6 +4/6 =
9/6 simplificando +3/2 = 1

4/5+2/3=
12/15 +15/15 = 27/15 simpificando 9/5

5/4 - 1/2=
10/8 - 4/8 =
6/8 simplificando 3/4
