Question

Explain why 1 13/7 does not represent a ratio and 1 3/7 : 3/7 does represent a ratio. Then tell how you express 1 3/7 as a ratio.

Answer 1

`1(13)/(7)`
`(1(3)/(7))/((3)/(7))`

It is not a ratio because it should not be expressed as a mixed number

so you can express the mixed number like a fraction

`\begin{gathered} 1(13)/(7) \\ ((7*1)+13)/(7) \\ (7+13)/(7) \\ \\ =(20)/(7) \end{gathered}`

20/7 is a ratio because is a fraction, the division between two numbers
