Answer 2

Answer:

Value of $x$  is $\frac{4}{75}$ .

Step-by-step explanation:

To find : the value of $x$  

Given ratio : $\frac{1}{15} : \frac{1}{4} :: x: \frac{1}{5}$

Solution :

• As we can see that in the given ratio of proportion value of $x$  is missing.
• In the given proportion , $\frac{1}{15}$ and $\frac{1}{5}$  are called as extremes whereas , $\frac{1}{4}$ and $x$ are called as means .  
• We know that ,

      Product of extremes = Product of means  

• Substituting values in above formula we find the value of $x$ .

         $\frac{1}{15} \times \frac{1}{5} = \frac{1}{4}\times x\\\\ \frac{1}{75} = \frac{x}{4} \\\\x = \frac{4}{75}$
