Przedstaw liczbę w postaci ułamka zwykłego
3,(8)
0,(369)
tylko dwa przykłady bo chcę zobaczyć czy dobrze robię
0,88888...=x
8,88888...=10x
8,88888...-0,888888...=10x-x
8=9x
x=8/9
3 8/9
0,369369...=x
369,369369...=1000x
369,369369...-0,369369...=1000x-x
369=999x
x=369/999
x=123/333
x=41/111
x = 3,(8)
10x = 38,(8)
10x- x = 38,(8) - 3,(8)
9x = 35
3,(8)=
x= 0,(369)
1000x= 369,(369)
1000x - x = 369,(369)- 0,(369)
999x = 369
0,(369) =
