a) \frac{3a}{5a}  =  \frac{3}{5}  \\ b) \frac{ {a}^{2}  - ab}{ad}  =  \frac{a(a - b)}{ad}  =  \frac{a - b}{d}

v) \frac{(m - 1)(m + 1)}{m(m + 1)}  =  \frac{m - 1}{m}  \\ g) \frac{ {y}^{2} }{y(y - 1)}  =  \frac{y}{y - 1}

д)

 \frac{(a + b) {}^{2} }{a + b)}  = a + b

Е)

 \frac{(a + 3b) {}^{2} }{(a - 3b)(a + 3b)}  =  \frac{a + 3b}{a - 3b}

Второй вариант аналогично делается
