Step 1:
: To find which number, when added to 1 / 3, produces an irrational number, we need to examine each option and determine whether the result is rational or irrational.

A rational number can be expressed as a fraction or a terminating or repeating decimal, while an irrational number is a non-repeating, non-terminating decimal.

Step 2:
: Option A: 2

When we add 2 to 1 / 3, we get a rational number: So, option A is not the answer.

Step 3:
: Option B: 2

Again, when we add 2 to 1 / 3, we get a rational number: So, option B is also not the answer.

Step 4:
: Option C: 2π

When we add 2π to 1 / 3, we get an irrational number, as π is irrational: So, option C is the correct answer.

Step 5:
: Option D: 0.166

When we add 0.166 to 1 / 3, we get a rational number, as 0.166 is a repeating decimal: So, option D is not the answer.

Final Answer

Option C: 2π produces an irrational number when added to 1 / 3.
