Question

a number whose 30% is equal to one-fifth of another number find the ratio of first number to the seond number

Answer 1

2:3 take the no.s x and y

Answer 2

Answer:

2:3

Step-by-step explanation:

Let the number be x

Let the another number be y

30% of first number = $30\% \times x$

One-fifth of another number =$\frac{1}{5} y$

We are given that a number whose 30% is equal to one-fifth of another number

$30\% \times x=\frac{1}{5} y$

$\frac{30}{100} \times x=\frac{1}{5} y$

$\frac{x}{y}=\frac{1}{5}\times\frac{100}{30}$

$\frac{x}{y}=\frac{100}{150}$

$\frac{x}{y}=\frac{10}{15}$

$\frac{x}{y}=\frac{2}{3}$

Hence the ratio of first number to the second number is 2:3
