Answer 2

The required "option c) $\dfrac{10}{14}$" is correct.

Step-by-step explanation:

We have,

$\dfrac{5}{7}$

To find, a rational number $\dfrac{5}{7}$ is equivalent to:

Check options:

a) $\dfrac{15}{17}$ , is not equivalent to $\dfrac{5}{7}$.

b) $\dfrac{25}{27}$ , is not equivalent to $\dfrac{5}{7}$.

c) $\dfrac{10}{14}$

Dividing numerator and denominator by 2, we get

= $\dfrac{\dfrac{10}{2} }{\dfrac{14}{2}}$

= $\dfrac{5}{7}$, is equivalent to $\dfrac{5}{7}$.

c) $\dfrac{10}{27}$,  is not equivalent to $\dfrac{5}{7}$.

Thus, the required "option c) $\dfrac{10}{14}$" is correct.
