а) ${\displaystyle \frac{2a(x+3)}{a^2(x+3)}=}$${\displaystyle \frac{2\cancel{a}\cancel{\left(x+3\right)}}{a\cancel{a}\cancel{\left(x+3\right)}}=}$${\displaystyle \frac{2}{a}}$;

б) ${\displaystyle \frac{m^2\cancel{{\left(m-n\right)}^2}}{n^2\cancel{{\left(m-n\right)}^2}}=}$${\displaystyle \frac{m^2}{n^2}}$;

в) ${\displaystyle \frac{6a(2-x)}{3a^2(2-x)}=}$${\displaystyle \frac{2\cdot \cancel{3a}\cancel{\left(2-x\right)}}{\cancel{3a}\cdot a\cancel{\left(2-x\right)}}=}$${\displaystyle \frac{2}{a}}$.
