To convert \( \frac{1}{3} \) of a tablespoon to teaspoons, it's important to know that there are 3 teaspoons in 1 tablespoon.
Now, we can calculate:
\[ \frac{1}{3} , \text{tablespoon} = \frac{1}{3} \times 3 , \text{teaspoons} \]
Calculating this gives us:
\[ \frac{1 \times 3}{3} = 1 , \text{teaspoon} \]
So, \( \frac{1}{3} \) of a tablespoon is equal to 1 teaspoon.
