$\dfrac{73}{99}$
The general formula to find the sum of an infinite Geometric series is given as: $S_{n}=\dfrac{a_1}{(1-r)}$ Here, we have the first term $a_1=\dfrac{73}{100}$ Now, $S_{n}=\dfrac{a_1}{(1-r)}=\dfrac{\dfrac{73}{100}}{1-\dfrac{1}{100}}$ Our answer is: $S_{n}=\dfrac{73/100}{99/100}=\dfrac{73}{99}$
