Question

3/7 : 5/8 2/3 : 4/7 4/5 : 3 1 целая 2/5 : 2/5

Answer 1

$\frac{3}{7} : \frac{5}{8} = \frac{3*8}{7*5} = \frac{24}{35}$

$\frac{2}{3} : \frac{4}{7} = \frac{2*7}{3*4} = \frac{7}{3*2} = \frac{7}{6} = 1\frac{1}{6}$

$\frac{4}{5} :3= \frac{4}{5*3} = \frac{4}{15}$

$1 \frac{2}{5} : \frac{2}{5} = \frac{7*5}{5*2} = \frac{7}{2}= 3\frac{1}{2} =3,5$
