Answer 1

$1) \frac{22p ^{4} q ^{2} }{99p^{5} q} = \frac{2*11p ^{4} q ^{2} }{9*11p^{5} q}=\frac{2q }{9p} \\ \\ 2) \frac{4a}{a ^{2} +5a} = \frac{4a}{a(a+5)} = \frac{4}{a+5} \\ \\ 3) \frac{7x-7y}{ x^{2} - y^{2} } = \frac{7(x-y)}{(x-y)(x+y)} = \frac{7}{x+y}$

Answer 2

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

$\frac{4a}{ a^{2}+5a } = \frac{4a}{a(a+5)} = \frac{4}{a+5}$

$\frac{7x-7y}{ x^{2} - y^{2} } = \frac{7(x-y)}{(x+y)(x-y)} = \frac{7}{x+y}$
