Explanation:

Given : Colin meets three wooden boards to repair his porch.The length he needs are 2.2 meters,2.82 meters,and 4.25 meters.He purchases a board that is 10 meters long and cuts the three sections.

To find : how much of the board that Colin purchased will be left.

Solution : We have given

He needs 2.2 meters,2.82 meters,and 4.25 meters.

He purchased = 10 m long board.

Total board he needs = 2.2 + 2.82 + 4.25 = 9.27 meter.
