Answer:
The quotient is -3
Step-by-step explanation:
we have
![\frac{a-3}{7}:\frac{3-a}{21}](https://tex.z-dn.net/?f=%5Cfrac%7Ba-3%7D%7B7%7D%3A%5Cfrac%7B3-a%7D%7B21%7D)
Multiply in cross
![\frac{(a-3)21}{(3-a)7}](https://tex.z-dn.net/?f=%5Cfrac%7B%28a-3%2921%7D%7B%283-a%297%7D)
Simplify
Remember that
![\frac{21}{7}=3](https://tex.z-dn.net/?f=%5Cfrac%7B21%7D%7B7%7D%3D3)
substitute
![\frac{(a-3)3}{(3-a)}](https://tex.z-dn.net/?f=%5Cfrac%7B%28a-3%293%7D%7B%283-a%29%7D)
we know that
![(3-a)=-(a-3)](https://tex.z-dn.net/?f=%283-a%29%3D-%28a-3%29)
substitute
![\frac{(a-3)3}{-(a-3)}=-3](https://tex.z-dn.net/?f=%5Cfrac%7B%28a-3%293%7D%7B-%28a-3%29%7D%3D-3)
