Bantuinnn , lupaa caranyaa hehe

Mengubah bilangan desimal ke pecahan biasa atau campuran

a) 8,07 = 8 + 0,07 = 8 + 7/100 = 8 7/100

b) 0,6666…. = x
10 x = 6,66666
10x – x = 6,6666.. – 0,6666..
9x = 6
x = 6/9 = 2/3

c) 1,636363… = 1 + 0,636363… = 1 + x
x = 0,6363…
100 x = 63,6363….
99 x = 63
x = 63/99 = 7/11

berarti bilangannya = 1 7/11
