Answer 1

Ответ:

Объяснение:

1) $\frac{18bc}{24c}=\frac{3*6bc}{4*6c}=\frac{3b}{4}$

2) $\frac{25a^2y}{15by} =\frac{5*5a^2y}{3*5by}=\frac{5a^2}{3b}$

3) $\frac{24a^3}{6ac} = \frac{4*6a*a^2}{6ac} =\frac{4a^2}{c}$

4) $\frac{27x^2y}{21xy^3} =\frac{9*3xy*x}{7*3xy*y^2}= \frac{9x}{7y^2}$

5) $\frac{-2a^6b^3}{a^3b^5}=-\frac{2a^3*a^3*b^3}{a^3*b^3*b^2} =-\frac{2a^3}{b^2}$

6) $\frac{x^7y^4}{x^5y^8} =\frac{x^5*x^2*y^4}{x^5*y^4*y^4} =\frac{x^2}{y^4}$

7) $\frac{42m^3n^5}{35mn^5}=\frac{6*7m^2*mn^5}{5*7mn^5} =\frac{6m^2}{7}$

8) $\frac{75p^4q}{150p^5q}=\frac{75p^4q}{2*75p*p^4q} =\frac{1}{2p}$
