Kathy has ribbons that have lengths of 7 inches, 10 inches, and 12 inches. Explain how she can use these ribbons to measure a length of 15 inches.
Thank you I hope this is right and not sarcasm thanks with love Bella Thomas
Place the 7-inch ribbon on the 10-inch ribbon. There will be 3 inches left over. Now put the 12-inch ribbon at the end of the 3-inch piece. Voila! You have 15 inches.
To measure a length of 15 inches using ribbons of lengths 7 inches, 10 inches, and 12 inches, Kathy can follow these steps:
1. Start by using the 12-inch ribbon. Place it alongside the length you want to measure, starting from one end. Let's assume this ribbon covers the first 12 inches.
2. Next, take the 7-inch ribbon and place it alongside the remaining length that needs to be measured. Align it with the end of the 12-inch ribbon, and it will cover an additional 7 inches.
3. At this point, Kathy has covered a total of 12 inches using the 12-inch ribbon and 7 additional inches using the 7-inch ribbon. This adds up to 19 inches.
4. To make the total measurement equal to 15 inches, Kathy needs to remove some length. Start by removing the 7-inch ribbon, leaving only the 12-inch ribbon in place.
5. Lastly, cut off 4 inches from the 12-inch ribbon. This will leave 8 inches of ribbon remaining, which added to the initial 12 inches will give a total length of 15 inches.
By combining the lengths of different ribbons strategically and making adjustments, Kathy can measure a length of 15 inches using the ribbons of 7 inches, 10 inches, and 12 inches.
