Question

Solve for x:4 1/2 is to 4 as x is to 12

Answer 1

`4(1)/(2)\text{ is to 4 as x is to 12}`
`\begin{gathered} 4(1)/(2)=4 \\ x=12 \end{gathered}`

the next thing is to cross multiply

`\begin{gathered} (9)/(2)=4 \\ x=12 \\ (9)/(2)*12=4* x \\ 54=4x \\ \text{Dividing both sides by 4} \\ x=(54)/(4) \end{gathered}`
`x=13(1)/(2)`

Hence the value of x is 13 1/2
