Answer 1

а)
$frac{4}{9} div frac{3}{8} = frac{4}{9} times frac{8}{3} = frac{32}{27} = 1 frac{5}{27}$

б)
$frac{3}{7} div frac{9}{14} = frac{3}{7} times frac{14}{9} = frac{2}{3}$

в)
$frac{86}{113} div frac{43}{51} = frac{86}{113} times frac{51}{43} = frac{102}{113}$

г)
$frac{27}{64} div 9 = frac{27}{64} times frac{1}{9} = frac{3}{64}$

д)
$8 div frac{2}{3} = frac{8}{1} times frac{3}{2} = 12$

е)
$7 div 3 = frac{7}{1} times frac{1}{3} = frac{7}{3} = 2 frac{1}{3}$

ж)
$2 frac{1}{7} div 1 frac{11}{14} = frac{15}{7} times frac{14}{25} = frac{6}{5} = 1 frac{1}{5} = 1.2$

з)
$3 frac{3}{5} div 1 frac{11}{25} = frac{18}{5} times frac{25}{36} = frac{5}{2} = 2 frac{1}{2} = 2.5$
