A. when sierra gets home, 3/4 of a sandwich is left in the refrigerator. she cuts the remaining part into three equal parts and eats two of them. what fraction of the whole sandwich did she eat?
b. write a number sentence to show your computation.

A. so she eats 2/3 of the pieces she cuts the sandwich into
that is 2/3 *OF* 3/4
(hint: of technically means * in math)
so 2/3 * 3/4
She eats 1/2 of the whole sandwich

b. Sierra eats 2/3 of the remaining 3/4 sandwich left in the refrigerator.

Hope this helps :)
