4t ESO/4.01 NOMBRES/4.01.1 Els nombres racionals 4.01.1.41A aprendre periòdic pur-fracció (1 xifra) Transforma el nombre periòdic pur  x = #a... a fracció.


a) Quantes xifres té el període? {#1}  Per quina quantitat cal multiplicar x? Per {#2}

b) Escriu les operacions i fes la resta:

{#3} x = {#4}... (amb #d decimals)
- x = {#5} ... (amb #d decimals)
{#6} x = {#7}  

 

Resultat SIMPLIFICAT: x = {#8} / {#9}
