Answer 1

To find an equivalent fraction to $\frac{5}{7}$, we can compare it to the options given:

1. $\frac{10}{21}$: This can be expressed as $\frac{5\times 2}{7\times 3}$ which does not equal $\frac{5}{7}$.
2. $\frac{15}{21}$: This can be simplified by dividing both the numerator and the denominator by 3: $\frac{15÷3}{21÷3}=\frac{5}{7}$. So, this is equivalent to $\frac{5}{7}$.
3. $\frac{7}{9}$: This does not relate to $\frac{5}{7}$.
4. $\frac{20}{21}$: This also does not equal $\frac{5}{7}$.

Therefore, the fraction that is equivalent to $\frac{5}{7}$ is $\frac{15}{21}$.
