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