The formula for the sum of an infinite geometric series, S=a1/1-r, may be used to convert

schepotkina [342]

Answer:

D. a1=23/100, r=1/100

Step-by-step explanation:

The repeating fraction can be written as the sum ...

$0.\overline{23}=0.23+0.0023+0.000023+\dots$

The first term is a1 = 0.23 = 23/100, and each successive term is shifted 2 decimal places to the right, so is multiplied by the common ratio r=1/100.
