Answer:the total amount that they recycled is 12 3/4 boxes
Explanation:
Maria's class recycled 2 2/8 boxes of paper in a month. Converting 2 2/8 boxes of paper in a month to improper fraction, it becomes
18/8 boxes of paper in a month.
They recycled another 10 4/8 boxes the next month. Converting 10 4/8 boxes to improper fraction, it becomes 84/8 boxes.
Therefore, the total amount of boxes that they recycled would be
18/8 + 84/8 = 102/8 boxes
Converting to whole number, it becomes
12 3/4 boxes
