Question

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 1

Serena use 1/2 cheese for the sandwiches 

Answer 2

So,

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


`(3)/(4) * (2)/(3) = (3 * 2)/(4 * 3) = (2 * 3)/(2 * 2 * 3)`

Cross-cancel.

`(1)/(2)`

Serena used one-half pound of cheese.

The correct option is C.
