$$ab + ac = a(b + c)$$

$$\frac{a}{b}-\frac{c}{d} =\frac{ad-bc}{bd}$$

$$a\left(\frac{b}{c}\right) =\frac{ab}{c}$$

$$\frac{a-b}{c-d}=\frac{b-a}{d-c}$$

$$\frac{(\frac{a}{b})}{c} =\frac{a}{bc}$$

$$\frac{a+b}{c}=\frac{a}{c}+\frac{b}{c}$$

$$\frac{a}{(\frac{b}{c})} =\frac{ac}{b}$$

$$\frac{ab+ac}{a}=b+c,a\neq0$$

$$\frac{a}{b}+\frac{c}{d} =\frac{ad+bc}{bd}$$

$$\frac{(\frac{a}{b})}{(\frac{c}{d})}=\frac{ad}{bc}$$
