$\frac{p - q}{p} \times ( \frac{p}{p - q} + \frac{p}{q} )$
​

Answer 1

Ответ:

$\frac{p-q}{p} * (\frac{pq+p(p-q)}{q(p-q)})=\frac{(p-q)(pq+p^{2}-pq) }{pq(p-q)}=\frac{p^{2} }{pq} =\frac{p}{q}$

Объяснение:

$\frac{p-q}{p} * (\frac{pq+p(p-q)}{q(p-q)})=\frac{(p-q)(pq+p^{2}-pq) }{pq(p-q)}=\frac{p^{2} }{pq} =\frac{p}{q}$
