My Algebra 1 teacher says that 0.999999.... does not equal 1 but guess what... I have 3 proofs for this!!!
1
x = 0.9999...
10x = 9.9999...
-x -.9999...
9x = 9
x = 1
1 = 0.9999...
2
.99999999
_____________
1| 1.0000000000
9
___________

Thus, 1/1 equals .9999...
3
1/3 = .3333.... 3/3 = .9999.... 1 = .9999....
