Lời giải:

Đặt $\frac{a}{b}=\frac{c}{d}=k$

$\Rightarrow a=bk, c=dk$. Khi đó:

$\frac{a-b}{b}=\frac{bk-b}{b}=\frac{b(k-1)}{b}=k-1(1)$

$\frac{c-d}{d}=\frac{dk-d}{d}=\frac{d(k-1)}{d}=k-1(2)$

Từ $(1); (2)\Rightarrow \frac{a-b}{b}=\frac{c-d}{d}$

-------------------

$\frac{2a+3b}{2a-3b}=\frac{2bk+3b}{2bk-3b}=\frac{b(2k+3)}{b(2k-3)}=\frac{2k+3}{2k-3}(3)$

$\frac{2c+3d}{2c-3d}=\frac{2dk+3d}{2dk-3d}=\frac{d(2k+3)}{d(2k-3)}=\frac{2k+3}{2k-3}(4)$

Từ $(3); (4)\Rightarrow \frac{2a+3b}{2a-3b}=\frac{2c+3d}{2c-3d}$

Lời giải:

a. Với $n$ nguyên khác -3, để $B$ nguyên thì:

$2n+9\vdots n+3$

$\Rightarrow 2(n+3)+3\vdots n+3$

$\Rightarrow 3\vdots n+3$

$\Rightarrow n+3\in\left\{\pm 1; \pm 3\right\}$

$\Rightarrow n\in\left\{-2; -4; 0; -6\right\}$

b. 

$B=\frac{2n+9}{n+3}=\frac{2(n+3)+3}{n+3}=2+\frac{3}{n+3}$

Để $B_{\max}$ thì $\frac{3}{n+3}$ max

Điều này đạt được khi $n+3$ là số nguyên dương nhỏ nhất

Tức là $n+3=1$

$\Leftrightarrow n=-2$

c. Để $B$ min thì $\frac{3}{n+3}$ min

Điều này đạt được khi $n+3$ là số nguyên âm lớn nhất 

Tức là $n+3=-1$

$\Leftrightarrow n=-4$
