b) 3,5767676 d) 0,2434343 e) 1,34666​

Answer 1

Resposta:

Explicação passo-a-passo:

a)  4,23686868... = 4 + 2368-23\9900 =

4 + 2345\9900 = 4.9900+2345\9900 =

41945\9900 = 8389\1980

b)  3,5767676... = 3 + 576-5\990 =

3 + 571\990 = 3.990+571\990 = 3541\990

c)  4,2555... = 4 + 25-2\90 = 4 + 23\90 =

4.90+23\90 = 383\90

d)  0,2434343... = 243-2\990 = 241\990

e)  1,34666... = 1 + 346-34\900 = 1 + 312\900 =

1.900+312\900 = 1212\900 = 404\300 =

202\150 = 101\75
