Answer 2

Ответ:

$\displaystyle \frac{x}{4}+\frac{2x}{3}=\frac{3x+8x}{12}=\frac{11x}{12}\\\\\\\frac{5b}{14}-\frac{b}{7}=\frac{5b-2b}{14}=\frac{3b}{14}\\\\\\\frac{m}{8}-\frac{n}{6}=\frac{3m-4n}{24}\\\\\\\frac{4}{x}-\frac{3}{y}=\frac{4y-3x}{xy}\\\\\\\frac{m}{4n}+\frac{m}{6n}=\frac{2m+3m}{12n}=\frac{5m}{12n}\\\\\\\frac{c}{b}-\frac{d}{3b}=\frac{3c-d}{3b}$
