Let's start by understanding the question. Rebecca has a photo with a width of 12 inches, and the length of the photo is 1½ times its width. To find the length, follow these steps:
1. Identify the width of the photo:
- The width of the photo is given as 12 inches.
2. Understand the ratio of the length to the width:
- The length of the photo is described as 1½ times the width.
3. Convert the ratio into a decimal for ease of multiplication:
- 1½ can be written as a mixed number, 1.5.
4. Calculate the length of the photo:
- To find the length, multiply the width by the ratio (1.5):
- Length = Width × Ratio
- Length = 12 inches × 1.5
5. Perform the multiplication:
- Length = 18 inches
Therefore, the length of the photo is 18 inches.
