Answer:
2 5/12 cups
Step-by-step explanation:
Map pours 3 2/3 cup of orange juice into measuring cup from a large container then he poured 1 1/4 cups back into the container
The amount of juice remaining in the measuring cup is calculated as:
3 2/3 - 1 1/4
= 3 - 1 + ( 2/3 - 1/4)
LCD = Lowest Common Denominator is 12
= 2 + (4 × 2 - 3 × 1/12)
= 2 + (8 - 3/12)
= 2 + 5/12
= 2 5/12 cups
Hence, the amount of juice remaining in the measuring cup = 2 5/12 cups of juice
