Pre-Algebra Examples

$\frac{9 - m}{m - 9}$

Step 1

Rewrite $9$ as $- 1 (- 9)$ .

$\frac{- 1 (- 9) - m}{m - 9}$

Step 2

Factor $- 1$ out of $- m$ .

$\frac{- 1 (- 9) - (m)}{m - 9}$

Step 3

Factor $- 1$ out of $- 1 (- 9) - (m)$ .

$\frac{- 1 (- 9 + m)}{m - 9}$

Step 4

Reorder terms.

$\frac{- 1 (m - 9)}{m - 9}$

Step 5

Cancel the common factor.

$\frac{- 1 (m - 9)}{m - 9}$

Step 6

Divide $- 1$ by $1$ .

$- 1$
