Question

Приведите дроби к наименьшему общему знаменателю:1/2 и 1/6; 3/8 и 3/4; 2/9 и 5/36; 3/7 и 7/35; 1/15 и 1/5; 7/16 и 3/8;​

Answer 1

а) $\frac{1}{2}$ и $\frac{1}{6}$ → $\frac{1*3}{2*3}$ и $\frac{1}{6}$ → $\frac{3}{6}$ и $\frac{1}{6}$

б) $\frac{3}{8}$ и $\frac{3}{4}$ → $\frac{3}{8}$ и $\frac{3*2}{4*2}$ → $\frac{3}{8}$ и $\frac{6}{8}$

в) $\frac{2}{9}$ и $\frac{5}{36}$ → $\frac{2*4}{9*4}$ и $\frac{5}{36}$ → $\frac{8}{36}$ и $\frac{5}{36}$

г) $\frac{3}{7}$ и $\frac{7}{35}$ → $\frac{3*5}{7*5}$ и $\frac{7}{35}$ → $\frac{15}{35}$ и $\frac{7}{35}$

д) $\frac{1}{15}$ и $\frac{1}{5}$ → $\frac{1}{15}$ и $\frac{1*3}{5*3}$ →$\frac{1}{15}$ и $\frac{3}{15}$

е) $\frac{7}{16}$ и $\frac{3}{8}$ → $\frac{7}{16}$ и $\frac{3*2}{8*2}$ → $\frac{7}{16}$ и $\frac{6}{16}$
