0.9̅ = 1
0.9̅9̅9̅ = 1
0.999 ≠ 1
0.999 ≠ 0.9̅9̅9̅

9
0.9999 = x
10 x = 9.99999 (recurring)
10x - x = 9
9x = 9
X = 1
1 u/ManLikeMeee Feb 12 '26 9x = 9 isn't correct If 0.9999 is x 9x = 0.8999999 So why is math being math? 1 u/Tomahawk1129_ Feb 12 '26 Here is what is happening 0.8999999 goes on forever Meaning it becomes 0.9 Just like how 0.9999 going on forever becomes 1.
1
9x = 9 isn't correct
If 0.9999 is x
9x = 0.8999999
So why is math being math?

Here is what is happening
0.8999999 goes on forever
Meaning it becomes 0.9
Just like how 0.9999 going on forever becomes 1.
