To solve this expression, we need to follow the order of operations (PEMDAS).

1/3 + 0,2115 ÷ 0,01 + 1/9 - 115 × 0,01 + 10/18

First, let's simplify the division and multiplication:

0,2115 ÷ 0,01 = 21,15
115 × 0,01 = 1,15

Now, the expression becomes:

1/3 + 21,15 + 1/9 - 1,15 + 10/18

Next, let's find a common denominator for the fractions:

1/3 = 6/18
1/9 = 2/18

Now, the expression becomes:

6/18 + 21,15 + 2/18 - 1,15 + 10/18

Combine the fractions:

(6 + 2 + 10) / 18 = 18/18 = 1

Now, the expression becomes:

1 + 21,15 - 1,15

Finally, add and subtract:

1 + 21,15 - 1,15 = 21

Therefore, the final answer is 21.
