I think .9 repeated does equal 1 because 1/3 = .3 repeated and 1/3 x 3 = 3/3 = 1
.3 repeated x 3 = .9 repeated. Get it?

Here's another way:
let n = .9 repeated
10n = 9.9 repeated
10n - n = 9n 9.9 repeated - n = 9.0
Therefore 9n = 9
9n / 9 = n 9 / 9 = 1
n = 1I think .9 repeated does equal 1 because 1/3 = .3 repeated and 1/3 x 3 = 3/3 = 1
