Observe as frações e transforme as em números racionais na forma decimal a)sete sobre nove 7/9 b)13/99 c)3/9 d)211/99

a) 1.1666666667

b) 0.1313131313

c) 0.3333333333

d) = 2.1313131313

Step-by-step explanation:

Observe as frações e transforme as em números racionais na forma decimal a)sete sobre nove 7/9 = 7÷ 9

1.1666666667

b)13/99 = 13÷ 99 = 0.1313131313

c)3/9 = 0.3333333333

d)211/99 = 2.1313131313

exa:

)

3+11
