Answer:
7/30
Step-by-step explanation:
i think you are talking about 0.2333333...
=0.2+0.03+0.003+0.0003+0.00003+...
=0.2+x
x=0.03+0.003+0.0003+0.00003+...
a1=0.03
r=(0.003)/(0.03)=(0.003)/0.030)=3/30=1/10=0.1
x=a1/(1-r)=0.03/(1-0.1)=.03/0.90=3/90=1/30
so 0.233333....=0.2+1/30=2/10+1/30=6/30+1/30=7/30
