“.9…” is repeating, but rational. So it’s actually “1” . Let’s do the math.
.9… / 3 = .3…
.3… = 1/3
1/3 x 3 = 3/3
.9… = 3/3
3/3 = 1
.9… = 1
Still not convinced? We’ll use algebra instead of fractions.
0.9… = x
10x = 9.9…
10x - 0.9… = 9
9x = 9
x = 1
I like the bleep-boo sounds of the command prompt scrolling by on computers.
