Step-by-step explanation:
There are a couple of different ways that division of fractions can be done.
1) "invert and multiply"
![\dfrac{14}{15}\div\dfrac{7}{5}=\dfrac{14}{15}\times\dfrac{5}{7}\\\\=\dfrac{14}{7}\times\dfrac{5}{15}=\boxed{\dfrac{2}{3}}](https://tex.z-dn.net/?f=%5Cdfrac%7B14%7D%7B15%7D%5Cdiv%5Cdfrac%7B7%7D%7B5%7D%3D%5Cdfrac%7B14%7D%7B15%7D%5Ctimes%5Cdfrac%7B5%7D%7B7%7D%5C%5C%5C%5C%3D%5Cdfrac%7B14%7D%7B7%7D%5Ctimes%5Cdfrac%7B5%7D%7B15%7D%3D%5Cboxed%7B%5Cdfrac%7B2%7D%7B3%7D%7D)

2) use the numerators when the denominators are the same
![\dfrac{14}{15}\div\dfrac{7}{5}=\dfrac{14}{15}\div\dfrac{21}{15}\\\\=\dfrac{14}{21}=\boxed{\dfrac{2}{3}}](https://tex.z-dn.net/?f=%5Cdfrac%7B14%7D%7B15%7D%5Cdiv%5Cdfrac%7B7%7D%7B5%7D%3D%5Cdfrac%7B14%7D%7B15%7D%5Cdiv%5Cdfrac%7B21%7D%7B15%7D%5C%5C%5C%5C%3D%5Cdfrac%7B14%7D%7B21%7D%3D%5Cboxed%7B%5Cdfrac%7B2%7D%7B3%7D%7D)
