Hi there,
The answer is 1/3 cup per teaspoon. Here’s how...
All you have to do is divided 2/3 by 2.
We have to put a 1 under the 2 to at least represent it as a fraction.
2/3 / 2/1
Next we flip 2/1 into 1/2.
2/3 / 1/2
Now we are going to multiply.
2x1=2
3x2=6
We get 2/6, simplifying that we get 1/3 cup per teaspoon.
