9=y

Answer 2

To find : the value of $y$

Given ratio : $4: 12 = 3: y$

Solution :

• As we can see that in the given ratio  forth ratio is missing.

• To find forth ratio to make ratio equivalent we can write $4: 12 = 3: y$

       as, $\frac{4}{12}=\frac{3}{y}$

• transposing like terms we get,

    $\Rightarrow \quad y=\frac{3 \times 12}{4}$

• On simplifying we get,

    $\begin{array}{l}\Rightarrow y =3\times 3 \\\Rightarrow y =9\end{array}$

Hence, value of $y$ is $9$ .
