Matt pours 3 2/3 cups of orange juice into a measuring cup from a large container. Then he pours 1 1/4 cups back into the container. How much orange juice remains in the measuring cup?
3 2/3 - 1 1/4 = ( 3 - 1 ) + ( 2/3 - 1/4 ) = 2 + ( 8/12 - 3/12 ) = 2 + 5/12 = 2 5/12 orange juice remains in the measuring cup.
