Answer 2

Answer:  The required ratio of the first number to the second number is 1 : 40.

Step-by-step explanation:  Given that 30 of a number is equal to three fourth of another number.

We are to find the ratio of the first number to the second number.

Let the two numbers be a and b.

Then, according to the given information, we have

$30\times a=\dfrac{3}{4}\times b\\\\\\\Rightarrow \dfrac{a}{b}=\dfrac{3}{4\times30}\\\\\\\Rightarrow \dfrac{a}{b}=\dfrac{1}{40}\\\\\Rightarrow a:b=1:40$

Thus, the required ratio of the first number to the second number is 1 : 40.
