Serena bought 3/4 pound of cheese. She used 2/3 of the cheese for sandwiches.

How much cheese did Serena use for sandwiches?

A.
lb 1/4

B. 1/3
lb

C.
lb 1/2

D.
lb 5/7



Answer :

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:

[tex] \frac{3}{4} * \frac{2}{3} = \frac{3 * 2}{4 * 3} = \frac{2 * 3}{2 * 2 * 3} [/tex]

Cross-cancel.
[tex] \frac{1}{2} [/tex]

Serena used one-half pound of cheese.

The correct option is C.
