Answer 1

2)$8 div frac{3}{5} = frac{40}{3} = 13 frac{1}{3} = 13.3333$
$frac{4}{7} div 3 = frac{4}{21}$
$14 div frac{14}{23} = frac{14 times 23}{14} = 23$
$3 div frac{13}{18} = frac{3 times 18}{13} = frac{54}{13} = 4 frac{2}{13}$
$1 frac{1}{25} div 2 frac{4}{7} = frac{26}{25} div frac{18}{7} = frac{26 times 7}{25 times 18} = \ = frac{182}{450} = frac{91}{225} = 0.404444$
3)
$3 div frac{1}{5} = 15$
$3 div frac{1}{8} = 24$
4)
$2x = frac{4}{9} \ x = frac{4}{9} div 2 = frac{2}{9}$
$frac{1}{2} x = 4 \ x = 4 div frac{1}{2} = 8$
$frac{3}{13} x = 1 \ x = 13$
$frac{4}{9} div x = 1 \ x = frac{4}{9} times 1 = frac{4}{9}$
$4 frac{5}{17} div x = 4 frac{5}{17} \ x = 1$
5)
$frac{35}{12} = frac{70}{24 } \ frac{7}{24} times 10 = frac{70}{24}$
в 10 раз
6)
$1 frac{4}{5} div 18 = frac{9}{5} div 18 = frac{9}{5 times 18} = frac{1}{10}$
7)
$frac{9}{25} div frac{20}{27} div frac{3}{8} = frac{9 times 27 times 8}{25 times 20 times 3} = 1296$
$(frac{1}{2} + frac{1}{3} ) div ( frac{1}{2} - frac{1}{3} ) = frac{5}{6} div frac{1}{6} = 5$
