Final answer:
The length of the remaining piece of ribbon is 0.45 m or 45 cm.
Step-by-step explanation:
To find the length of the remaining piece of ribbon, we need to subtract the total length of the three pieces (85 cm each) from the original length of the ribbon (3 m).
Each piece is equivalent to 0.85 m, so the total length of the three pieces is 2.55 m (0.85 m × 3).
To find the remaining length, we subtract 2.55 m from 3 m:
3 m - 2.55 m = 0.45 m or 45 cm.
Therefore, the length of the remaining piece of ribbon is 0.45 m or 45 cm.
