From a ribbon which is 22m long,two pieces of length26.4m and 32.10m are cut off.what is the length of the remaining ribbon?

22 - 26.4 - 32.1 = a negative!

Please reread your question and see what needs correcting.

To find the length of the remaining ribbon, you need to subtract the lengths of the two pieces that were cut off from the original length of the ribbon.

Here's how you can calculate it step by step:

1. Start with the original length of the ribbon, which is 22m.
2. Subtract the length of the first piece that was cut off, which is 26.4m.
Calculation: 22m - 26.4m = -4.4m
Since the result is negative, it means that the first piece is longer than the original length of the ribbon. Thus, the remaining ribbon after cutting off the first piece is 0m.
3. Subtract the length of the second piece that was cut off, which is 32.10m.
Calculation: 0m - 32.10m = -32.10m
Again, the result is negative, which means the second piece is longer than the remaining ribbon after cutting off the first piece. Therefore, the final length of the remaining ribbon is 0m.

So, the length of the remaining ribbon is 0m.
