1º)3/4 + 5/4 + 2/4=10/4 
2º)2/5 +6/5 +1/5 =9/5 
3º)13/24 + 10/23 =23/23 
4º)4/9 +7/6 = 29/18 
5º)1/3 +1/6 =9/18 
6) 3/7 + 4/7 = 6/7

8) ¼ + 2/3 = 11/12
9) ½ + 4/5 = 13/10


restas

1) 7/9 – 3/9 = 4/9
2) 10/3 – 5/3 = 5/3
3) 7/6 - 5/6 = 2/6
4º)7/2 - 4/2 =3/2 
5º) 7/9 - 2/9=5/9 
6º) 14/3 - 10/3= 4/3 
7) 4/4 -8/16 = 32/64
8) 6/12 – 1/4 = 12/48
