Answer:

5%

Step-by-step explanation:

Answer 2

Step-by-step explanation:

Let the first number be A

Let second number be B

Let third number be X

First number =

$\frac{10}{100} \times x$

$\frac{x}{10}$

Second Number =

$\frac{20}{100} \times x$

$\frac{2}{10} \times x$

$\frac{1}{5} \times x$

$\frac{x}{5}$

Ratio =

A:B = A/B

$\frac{ \frac{x}{10} }{ \frac{x}{5} }$

$\frac{x}{10} \times \frac{5}{x}$

$\frac{5x}{10x}$

$\frac{5}{10}$

$\frac{1}{2}$

Therefore the ratio is :

1:2
