Let X = 1.9999....... ---------- (1)
Here, The bar is only for 9, that implies, we have to multiply both sides by 10.
10 × X = 1.999... × 10
10X = 19.9999.....--------(2)
Subtracting (1) from (2), we get,
10X - X = 19.999... - 1.999...
9X = 18
X = 18/9
Therefore, X = 2 (or) 18/9.
Hope it helps you!
