Question

Give three rational numbers equivalent to:
$$\dfrac{7}{11}$$

Answer 1

Equivalent rational numbers are
$$\Rightarrow \dfrac{7}{11}$$
$$\Rightarrow \dfrac{7}{11}=\dfrac{7\times2}{11\times2}=\dfrac{14}{22}$$
$$\Rightarrow \dfrac{7}{11}=\dfrac{7\times3}{11\times3}=\dfrac{21}{33}$$
$$\Rightarrow
\dfrac{7}{11}=\dfrac{7\times4}{11\times4}=\dfrac{28}{44}$$

Therefore, equivalent rational numbers of given number are
$$\dfrac{14}{22},\dfrac{21}{33}$$ and $$\dfrac{28}{44}$$
