Question

determine a fração geratriz das dizimas A) 5,121212 B) 0,342342342

Answer 1

Vamos lá:

A) 5,121212
x= 5,121212×100

100x= 512,121212
- x= 5,121212
----------------------------
99x= 507

x= 507/99


B) 0,342342342

x= 0,342342342×1000

1000x= 342,342342
- x= 0,342342
---------------------------------
999x= 342

x= 342/999
