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

Step 1

Factor $- 1$ out of $a$ .

$\frac{- 1 (- a) - b}{b - a}$

Step 2

Factor $- 1$ out of $- b$ .

$\frac{- 1 (- a) - (b)}{b - a}$

Step 3

Factor $- 1$ out of $- 1 (- a) - (b)$ .

$\frac{- 1 (- a + b)}{b - a}$

Step 4

Reorder terms.

$\frac{- 1 (- a + b)}{- a + b}$

Step 5

Cancel the common factor.

$\frac{- 1 (- a + b)}{- a + b}$

Step 6

Divide $- 1$ by $1$ .

$- 1$
