Tomas used 3 1/3 cups of flour and now has 1 2/3cups left. which equation can he use to find f, the number of cups of flour he had to begin with? f+3 1/3=1 2/3 f-3 1/3=1 2/3 3 1/3f=1 2/3 f/3 1/3=1 2/3

For this case we have that the variable "f" represents the number of cups of flour that Tomas had initially.

If of that amount Luis used of cups of flour, then we have the following expression:

If Luis has cups of flour left, then we have the following equation:

Finally, the equation that represents the given situation is:
