The formula for the sum of an infinite geometric series, s=a1/1-r, may be used to convert o. 23 to a fraction. What are the values of a1and r?

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
