c) 4/7 + 5/7 +6/7 - 8/7 =



d)9/(1 3)- 5/13=



e) 8/12- 4/12=

​

Answer 1

Resposta:

Explicação passo-a-passo:

a)7/9 + 5/9 + 2/9= (7+5+2)/9 = 14/9

b)3/10 + 9/10 + 5/(10 ) -6/10= (3+9+5-6)/10 = 11/10

c) 4/7 + 5/7 +6/7 - 8/7 = (4+5+6-8)/7 = 7/7= 1

d)9/13 - 5/13= (9-5)/13 = 4/13

e) 8/12- 4/12= (8-4)/12 = 4/12 = 1/3
