1. \(\frac{4a+8b}{4a}=\frac{4(a+2b)}{4a}=\frac{a+2b}{a}\).
2. \(\frac{5x-10y}{3x-6y}=\frac{5(x-2y)}{3(x-2y)}=\frac{5}{3}\).
3. \(\frac{x^2-25}{2x-10}=\frac{(x-5)(x+5)}{2(x-5)}=\frac{x+5}{2}\).
4. \(\frac{6x^2-3x}{4-8x}=\frac{3x(2x-1)}{-4(2x-1)}=-\frac{3x}{4}\).
5. \(\frac{m^2-16}{m^2+8m+16}=\frac{(m-4)(m+4)}{(m+4)^2}=\frac{m-4}{m+4}\).
6. \(\frac{b^5-b^3}{b^2-b^4}=\frac{b^3(b^2-1)}{b^2(1-b^2)}=\frac{b^3(b^2-1)}{-b^2(b^2-1)}=-b\).

Ответ: 1) \(\frac{a+2b}{a}\); 2) \(\frac{5}{3}\); 3) \(\frac{x+5}{2}\); 4) \(-\frac{3x}{4}\); 5) \(\frac{m-4}{m+4}\); 6) \(-b\).
