Hello from MrBillDoesMath! 
 
Answer: 
2291/990
 
Discussion: 
 Let
x = 2.3141414...... then
10x = 23.141414... (*) 
and
1000x = 2314.141414..... (**)
Subtract (*) from (**):
1000x - 10x = (2314 + .141414....) - (23 + .141414....)
990x = 2314 - 23 as the decimal parts cancel
990x = 2291
x = 2291/990
Thank you, 
 
MrB
