Since there is a minus sign on one of the terms in the denominator and a minus sign on the numerator, if we divide by a negative number, then we will only have 1 minus sign in the denominator. I prefer the form:

$ \displaystyle \frac{a}{b-c}$

over:

$ \displaystyle \frac{-a}{c-b}$

Even though they are equivalent, I like fewer negatives. Then if we look at 550 and 20000, we see that 50 is the GCD, so dividing each term by -50 will result in the simplest terms in the form with fewer negative signs.
