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.
Hence 9.27 meter board he need to use .
Board left = 10 - 9.27 = 0.73 meter.
Therefore, 0.73 meter board that Colin purchased will be left.
