$\frac{c}{c - k} \div \frac{d}{k - c}$

Step 1

To divide by a fraction, multiply by its reciprocal.

$\frac{c}{c - k} \cdot \frac{k - c}{d}$

Step 2

Multiply $\frac{c}{c - k}$ by $\frac{k - c}{d}$ .

$\frac{c (k - c)}{(c - k) d}$

Step 3

Cancel the common factor of $k - c$ and $c - k$ .

Step 3.1

Factor $- 1$ out of $k$ .

$\frac{c (- 1 (- k) - c)}{(c - k) d}$

Step 3.2

Factor $- 1$ out of $- c$ .

$\frac{c (- 1 (- k) - (c))}{(c - k) d}$

Step 3.3

Factor $- 1$ out of $- 1 (- k) - (c)$ .

$\frac{c (- 1 (- k + c))}{(c - k) d}$

Step 3.4

Reorder terms.

$\frac{c (- 1 (c - k))}{(c - k) d}$

Step 3.5

Cancel the common factor.

$\frac{c (- 1 (c - k))}{(c - k) d}$

Step 3.6

Rewrite the expression.

$\frac{c \cdot (- 1)}{d}$

$\frac{c \cdot (- 1)}{d}$

Step 4

Simplify the expression.

Step 4.1

Move $- 1$ to the left of $c$ .

$\frac{- 1 \cdot c}{d}$

Step 4.2

Move the negative in front of the fraction.

$- \frac{c}{d}$

$- \frac{c}{d}$
