Given:

A rational number $\frac{5}{7}$ .

To find:

A rational number $\frac{5}{7}$ is equivalent to = ?  

Rational Number :

Rational number can be expressed as fractions or integers.

Rational number consists of positive and negative integers.

Rational number are represented in the form of $\frac{P}{Q}$.

Example for rational number :

To find  whether the number "2" is rational number or not .

Here, number "2" can be written in rational form $\frac{2}{1}$ .

Hence, number "2" is a rational number.

Explanation :

The answer of this question is we can multiply numerator and denominator by same number that is 2,3,4,5 what ever in option we can select in that way.

So   $\frac{5}{7} = \frac{5\times2}{7\times2} = \frac{5\times3}{7\times3}$ 

       $\frac{5}{7}= \frac{10}{14} =\frac{15}{21}$

Therefore, $\frac{5}{7}$ is equivalent to $\frac{10}{14} = \frac{15}{21} = \frac{20}{28}$.
