1 tablespoon is equivalent to 3 teaspoons

To find the equivalence of 3 1/3 tablespoons in teaspoons, we can use the next proportion:


\frac{1\text{ tablespoon}}{3(1)/(3)\text{ tablespoon}}=\frac{3\text{ teaspoons}}{x\text{ teaspoons}}

Solving for x:


\begin{gathered} 1\cdot x=3\cdot3(1)/(3) \\ x=3\cdot3+3\cdot(1)/(3) \\ x=9+1 \\ x=10 \end{gathered}

Barbara must use 10 teaspoons
