Resposta :
B)2,83333.. = 2 + 0,83333.. = 2 + (83 - 8) / 90 = 2 + 75/90 = 2 + 5/6 = 12/6 + 5/6 = 17/6
Geratriz = 17/6
C)4,88888.. = 4 + 8/9 = 36/9 + 8/9 = 44/9
Geratriz = 44/9
D)123,548484848... = 123 + 0,54848.. = 123 + (548 - 5) / 990 = 123 + 543/990 = 181/330
= (123)(330)/330 + 181/330 = 40.771/330
Geratriz = 40.771/330
