The box of cereal has 1312 cups, and Maria's children eat 112 cups each day. To find out how many days the box will last, divide the total amount of cups in the cereal by how many cups are eaten each day:
[tex]1312 \div 112 = 11.7[/tex]
Round the number to the nearest ones place:
11.7
7 > 5
11.7 -> 12
We round this number because on the 12th day, there's cereal still remaining in the box.
The box of cereal will last for 12 days.
