Question

writhg about Equivalent Ratios If you know the ratio of inches to centimeters is 1 to 2.54, how can you find the number of centimeters equivalent to 9 inches? What is the relationship between centimeters and inches?

Answer 1

We have the following:

`\begin{gathered} 1\text{ in= 2.54 cm} \\ \end{gathered}`

therefore:

`9\text{ in }\cdot\text{ }\frac{2.54\text{ cm}}{1\text{ in}}=22.86\text{ cm}`

We can also say that 1 cm is equal to 0.3937 in (1/2.54)
