Answer:
43,721/99,999
Explanation:
A non-terminating, repeating decimal can be written as a fraction.
How many digits repeat?
If the digits 43721 repeat, and the decimal number is
0.437214372143721..., then we can convert it into a fraction.
Let x = 0.437214372143721... Eq. 1
Then 100,000x = 43,721.4372143721... Eq. 2
Now we subtract Eq. 1 from the Eq. 2.
100,000x = 43,721.4372143721...
(-) x = 0.4372143721...
--------------------------------------------------
99,999x = 43,721
x = 43,721/99,999
Answer: 43,721/99,999
