Question 319620
Express each given irrational numbers as a quotient of two numbers.
Ex. a) 0.1111... 
n = 0.11111...
10n = 1.1111...
1n = 00.1111....
------------------ Subtract
9n = 1
n = 1/9
---------
b) 0.585858...
----------------------
c) -3.173173173..
Ignore the -3 for now
n = 0.173173...
1000n = 173.173173...
1n = 0.173173...
------------------- Subtract
999n = 173
n = 173/999
--> -3 173/999
------------------
d) 4.0121212...
