Step-by-step explanation:

that's just the way it be.

Answer 2

-3

Explanation:

The given expression is:

`((a-3)/(7) )/((3-a)/(21) )`

We can rewrite this as:

`(a-3)/(7)/ (3-a)/(21)`

`(a-3)/(7)* (21)/(3-a)`

Factor -1 out of the first numerator:

`(-(3-a))/(7)* (21)/(3-a)`

Cancel out the common factors;

`(-1)/(1)* (3)/(1)=-3`
