Question

Qual a função geratriz de cada dízima a seguir?

A) 0,55555

B) 0,232323

C) 0,575757

D) 0,34893489

Answer 1

a) x=0,55555
10x=5,55555
10x=5,55555
- x=0,55555
9x=5
x=5/9

b) x=0,2323232
10x=2,32323232
100x=23,23232
100x=23,23232
- x= 0,23232
99x=23
x=23/99

c) x= 0,575757
10x=5,7575757
100x=57,57575
100x=57,57575
- x= 0,57575
99x=57
x=57/99= 19/33
