Given that there are 3 teaspoons in 1 tablespoon,
![1\text{ Tbsp}=3\text{ tsp}](https://img.qammunity.org/2023/formulas/mathematics/college/7f2qfwmq53ov8njvns2uvfkgrpr5cp8p6d.png)
It is asked to determine the number of teaspoons corresponding to 3 tablespoons.
This can be calculated as follows,
![\begin{gathered} 3\text{ Tbsp} \\ =3\cdot(1\text{ Tbsp}) \end{gathered}](https://img.qammunity.org/2023/formulas/mathematics/college/4h4nun5xyr1e6hayrrxtcezrf90yu6uexs.png)
Substitute the given conversion value,
![\begin{gathered} =3\cdot(3\text{ tsp}) \\ =9\text{ tsp} \end{gathered}](https://img.qammunity.org/2023/formulas/mathematics/college/xya2m3kzun1hi7ei8gd7ky50s01xloyovf.png)
Thus, there are 9 teaspoons in 3 tablespoons.
