Question

Solve the proportion using TWO different methods.4/9= 28/xMethod 1Method 2

Answer 1

Method 1

`(4)/(9)=(28)/(x)`
`\begin{gathered} 4x=28*9 \\ x=(252)/(4)=63 \end{gathered}`

Method 2

`(4)/(9)-(28)/(x)=0`
`(4x-252)/(9x)=0`
`\begin{gathered} 4x-252=0*9x \\ 4x-252=0 \end{gathered}`
`\begin{gathered} 4x=252 \\ x=(252)/(4)=63 \end{gathered}`

Therefore, x=63.
