Video Transcription

Problem number 9. Edmund cut a ribbon as shown in the picture. How many pieces of ribbon did he end up with? A, 9, B, 10, C, 11, D, 12, or E, 13.  When we have a string and we cut it once, we actually get 2 pieces of string. If we cut it twice, we get 3 pieces. We can apply this to this ribbon. It's going to be a lot  easier to count the number of cuts than the individual pieces. So let's count the number of times the scissors crossed the ribbon. 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11. We have  11 cuts, which means that there will be 12 pieces of ribbon. We can double check our work. One piece, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12. So the answer is D. Edmund ended  up with 12 pieces of ribbon.

Video Summary

Edmund cut a ribbon and wanted to determine how many pieces he ended up with. By counting the number of cuts made in the ribbon, which were 11, it was determined that there would be 12 pieces of ribbon. This is because each cut increases the number of pieces by one. After verifying by counting the individual pieces, it confirmed there were indeed 12 pieces. Therefore, the correct answer is D.
