It takes \( 7 / 12 \) foot of ribbon to make a bookmark. How many feet of ribbon will it take to make 15 bookmarks?

To find out how much ribbon is needed for 15 bookmarks, simply multiply the amount of ribbon required for one bookmark by the total number of bookmarks. So, it will be \( \frac{7}{12} \) foot times 15: \[ \text{Total ribbon} = \frac{7}{12} \times 15 = \frac{7 \times 15}{12} = \frac{105}{12} = 8.75 \text{ feet} \] So, you will need 8.75 feet of ribbon to make 15 bookmarks! Now, let’s dive into how this kind of math can make your crafting life so much easier and avoid common mistakes such as forgetting to convert units. Don't underestimate the power of double-checking your multiplication!
