To find a smaller scale drawing of the original photograph, we need to look for dimensions that are proportional to the original dimensions of 6 inches by 4 inches while being smaller in size.
The original dimensions can be expressed as a ratio:
6 inches (width) : 4 inches (height) = 3 : 2
Now we can analyze each of the provided options to see which maintains the same ratio and is smaller than the original dimensions:
-
1 inch by 0.5 inches:
- Ratio = 1 : 0.5 = 2 : 1 (not proportional)
-
1.5 inches by 1 inch:
- Ratio = 1.5 : 1 = 3 : 2 (proportional and smaller)
-
12 inches by 8 inches:
- Ratio = 12 : 8 = 3 : 2 (proportional, but larger than the original)
-
2 inches by 1 inch:
- Ratio = 2 : 1 (not proportional)
The only option that maintains the same ratio of 3:2 and is smaller than the original dimensions (6 inches by 4 inches) is 1.5 inches by 1 inch.
So, the correct answer is: 1.5 inches by 1 inch.
