Escreva a fração geratriz das dizimas abaixo:
a)
x = 2,3262626...(10) multiplica
10x = 23,262626...(100)multiplica
1000x = 2326,262626...
1000x = 2326,262626...
10x = 23,262626... subtrai
----------------------------------------------
990x = 2303,0000000...
990x = 2303
x = 2303/990
assim
2,3262626... = 2303/990
a)
x = 2,3262626...(10) multiplica
10x = 23,262626...(100)multiplica
1000x = 2326,262626...
1000x = 2326,262626...
10x = 23,262626... subtrai
----------------------------------------------
990x = 2303,0000000...
990x = 2303
x = 2303/990
assim
2,3262626... = 2303/990

x=2,3262626...
10 x=23,262626...
100 x=232,62626...
1000 x=2326,2626...
100000 x=232626,26...
100000 x - 1000 x=232626,26...- 2326,2626...
99000 x = 230300
x= 230300/99000 = 2,3262626...
10 x=23,262626...
100 x=232,62626...
1000 x=2326,2626...
100000 x=232626,26...
100000 x - 1000 x=232626,26...- 2326,2626...
99000 x = 230300
x= 230300/99000 = 2,3262626...
