Question

transforme as frações: a)1,333... b)0,35111...

Answer 1

Transforme as frações:
 a)1,333...
 
                    x       =      1,333...(10)multiplica
                10x       =    13,333...

10x  = 13,333...
    x   =  1,333...SUBTRAI
---------------------------------
  9X   = 12,000...

9x = 12
x = 12/9

assim
1,333... = 12/9  

ou simplificar
1.333... = 12/9   ( divide AMBOS por 3)
1,333...=   4/3


 b)0,35111...


              x     =      0,35111...                (100)multiplica
         100x    =    35,11111...                    (10)multiplica
      1000X    =   351,11111...

1000x  = 351,111...
  100x  =   35,111...  SUBTRAI
----------------------------------------
  900x  = 316,000...

900x = 316
x = 316/900

assim

0,35111... = 316/900
