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

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

в) ${\displaystyle \frac{4x(x-y)}{7y{(x-y)}^2}=}$${\displaystyle \frac{4x\cancel{\left(x-y\right)}}{7y(x-y)\cancel{\left(x-y\right)}}=}$${\displaystyle \frac{4x}{7y\left(x-y\right)}}$.
