Answer: The length of the shorter side is [tex]1\frac{1}{3}[/tex] inches (option C).
Step-by-step explanation:
- The ratio of the original picture is [tex]\frac{4}{12}[/tex].
- The ratio of the new picture is [tex]\frac{x}{4}[/tex].
- In order to get the longest side to 4, we divided by 3. As a result, we must divide 4 (the original shorter side) by 3 to find the new length.
- [tex]\frac{4}{3}[/tex] = [tex]1\frac{1}{3}[/tex]
