Question

Jadikan bilangan ini menjadi bilangan rasional
a. 0,3333
b.0,121212
c.3,154154154

Answer 1

A.misalkan x = 0,3333
10x=3,3333
x=0,3333
-------------------- -
9x=3
x=3/9
x=1/3

b.misalkan x=0,121212
100x=12,121212
x= 0,121212
--------------------------- -
99 x =12
x = 12/99
x = 4/33

c. misalkan x=3,154154154
1000x=3154,154154154
x= 3,154154154
---------------------------------------- -
999 x = 3151
x =3151/999
