Step 1:Let's solve this step by step:
Step 2:: Understand the given information
- We know that 2 inches = 5 centimeters - We need to find the correct conversion relationship
Step 3:: Set up the conversion ratio
\frac{2 \text{ inches}}{5 \text{ centimeters}} = \frac{x \text{ inches}}{y \text{ centimeters}}
Step 4:: Cross multiply to find the relationship
2y = 5x
Step 5:: Rearrange the equation to express the relationship
x = \frac{2y}{5}
Step 6:: Analyze the possible conversion relationships
- This means that for any number of inches, you would multiply by $$\frac{2}{5}$$ to get the equivalent number of centimeters
Step 7:: Verify the conversion
- Then 1 inch would equal $$\frac{5}{2} = 2.5$$ centimeters
- If 2 inches = 5 centimeters
Final Answer
The correct conversion is 1 inch = 2.5 centimeters.
