Serena use 1/2 cheese for the sandwiches

So,

Serena starts with three fourths pounds of cheese, and uses two thirds of it.  That is equivalent to the following expression:

\(\frac{3}{4} * \frac{2}{3} = \frac{3 * 2}{4 * 3} = \frac{2 * 3}{2 * 2 * 3}\)

Cross-cancel.
\(\frac{1}{2}\)

Serena used one-half pound of cheese.

The correct option is C.
