Step-by-step explanation:

You can divide fractions a couple of ways:

1. Invert the denominator and multiply

$\dfrac{7}{11}\div\dfrac{21}{55}=\dfrac{7}{11}\times\dfrac{55}{21}=\dfrac{55\cdot7}{11\cdot21}=\boxed{\dfrac{5}{3}}$

2. Make both fractions have the same denominator and use the ratio of their numerators

$\dfrac{7}{11}\div\dfrac{21}{55}=\dfrac{35}{55}\div\dfrac{21}{55}=\dfrac{35}{21}=\boxed{\dfrac{5}{3}}$
