plissss bantu
pakai cara kerja nya ​

a. 0,9999...

x = 0,999...

10x = 9,999...

-------------------- -

-9x = -9

x = -9/-9 = 1 (terbukti)

b. 0,474747...

x = 0,474747...

100x = 47,474747...

---------------------------- -

-99x = -47

x = -47/(-99)

= 47/99 (terbukti)

d. 0,466666...

x = 0,46666...

10x = 4,6666...

100x = 46,6666...

---------------------------- -

-90x = -42

x = -42/-90

= 21/45 (terbukti)

f. 1,246666...

x = 1,24666...

100x = 124,6666...

1000x = 1246,6666...

------------------------------- -

-900x = -1.122

x = -1.122/-900

= 187/150 (terbukti)
