Answer 2

Answer:

The ratio will be  12 : 30 :: 20 : 50

Step-by-step explanation:

The ratio which is needed to be calculated :

12 : 30 :: 20 : ?

Let the required number be x'

So, The ratio becomes - 12 : 30 :: 20 : x

Now, Reducing the ratio in the fraction form :

$\implies \frac{12}{30}=\frac{20}{x}\\\\\implies 12\times x =20\times 30\\\\\implies x = \frac{20\times 30}{12}\\\\\implies x = \frac{600}{12}\\\\\implies x = 50$

Thus, The required value of x = 50

Hence, The ratio will be  12 : 30 :: 20 : 50
