Answer 1

Объяснение:

1)

$\frac{a(x + 2)}{b(x + 2)} = \frac{a}{b}$

2)

$\frac{22p {}^{4} q {}^{2} }{99p {}^{5}q } = \frac{2q}{9p}$

3)

$\frac{7a + 7x}{5a + 5x} = \frac{7}{5} = 1 \frac{2}{5} = 1.4$

4(

$\frac{3a - 6b}{8b - 4a} = - \frac{3}{4} = - 0.75$

5)

$\frac{8x {}^{2} - 4xy}{12x {}^{3} } = \frac{4x \times (2x - y)}{12x {}^{3} } = \frac{2x - y}{3x {}^{2} }$
