№296

\displaystyle \frac{2*5}{3*6}=\frac{2*5}{3*2*3}=\frac{5}{3*3}=\frac{5}{9}\\\\\\\frac{2*7}{9*4}=\frac{2*7}{9*2*2}=\frac{7}{9*2}=\frac{7}{18}\\\\\\\frac{3*5}{20*2}=\frac{3*5}{4*5*2}=\frac{3}{4*2}=\frac{3}{8}\\\\\\\frac{4*3}{9*7}=\frac{4*3}{3*3*7}=\frac{4}{3*7}=\frac{4}{21}

№ 297

\displaystyle \frac{10 * 3}{23 * 10}=\frac{3}{23}\\\\\\\frac{10 * 2}{21 * 30}=\frac{10 * 2}{21 * 3 * 10}=\frac{2}{21 * 3}=\frac{2}{63}\\\\\\\frac{4 * 5}{15 * 16}=\frac{4 * 5}{3 * 5 * 4 * 4}=\frac{1}{12}\\\\\\\frac{8*9}{27*16}=\frac{2 * 4* 3 * 3}{3 * 3 * 3*4*2*2}=\frac{1}{3*2}=\frac{1}{6}
