<PRE><B>Question 356817</B>
If someone could explain to me how 69.99999 = 70, I would be very grateful!
--------------------------
Let x = 69.999999 endlessly
----
Then 10x = 699.99999endlessly
-----
Subtract the 1st equation from the 2nd to get:
9x = 630
---
Divide by 9 to get:
x = 70
--------
Therefore x = 69.99999... = 70
===================================
Fact: Every repeating decimal can be written as a/b
where a and b are integers and b is not zero.
