The digits of Pi are written in a 113X355 grid with 113 rows and 355 columns, one digit in each square, starting from the top left and going across and then down.

(So, the first row starts with 3,1,4,1,5,9,2....) Alice calculates each of the 113 row sums, and finds their average bob calculates each of the 355 column sums, and finds their average. What is the  ratio of  Alice's average to Bob's average?
