Question

how do i find as "n" as the numerator and 10 as the denominator = 3 as the numerator and 9 as the denominator or n/10 = 3/9??

Answer 1

`(n)/(10)=(3)/(9)\text{ }`

The first step to find the value of "n" is to cross multiply, this means to multiply the numerator of one fraction by the denominator of the other as shown below:

`9\cdot n\text{ = 3}\cdot10`

We now need to isolate the "n" variable to find its value.

`\begin{gathered} 9\cdot n\text{ = 30} \\ n\text{ = }(30)/(9)\text{ = }(10)/(3) \end{gathered}`

The variable n is equal to 10/3 or 3.3333...
