Answer 1

Пошаговое объяснение:

$1 frac{1}{7} times 3 frac{1}{16} = frac{8 times 49}{7 times 16} = frac{7}{2} = 3 frac{1}{2} = 3.5 \ - - - \ frac{16}{81 } times frac{45}{57} times frac{19}{4} = frac{4 times 15 times 19}{81 times 19 times 1} = frac{60}{81} = frac{20}{27}$

$frac{1}{3} div frac{2}{5} = frac{1 times 5}{3 times 2} = frac{5}{6} \ frac{1}{2} div frac{1}{5} = frac{5}{2} = 2 frac{1}{2}$

$6 div frac{2}{3} = 6 times frac{3}{2} = 3 times 3 = 9 \ 8 div frac{1}{3} = 8 times 3 = 24 \ frac{1}{2} div 4 = frac{1}{2} times frac{1}{4} = frac{1}{8} \ frac{2}{3} div 7 = frac{2}{3} times frac{1}{7} = frac{2}{21}$

$frac{3}{5} div 6 = frac{3}{5} times frac{1}{6} = frac{1}{5 times 2} = frac{1}{10} \ frac{3}{4} div frac{15}{4} = frac{3 times 4}{4 times 15} = frac{1}{5} \ frac{15}{16} div frac{3}{10} = frac{15 times 10}{16 times 3} = frac{5 times 5}{8} = frac{25}{8} = 3 frac{1}{8}$

$frac{36}{49} div frac{6}{7} = frac{36 times 7}{49 times 6} = frac{6}{7} \ 1 frac{7}{9} div 3 frac{3}{4} = frac{16}{9} div frac{15}{4} = frac{16 times 4}{9 times 15} = frac{64}{135} \ frac{35}{48} div frac{21}{32} = frac{35 times 32}{48 times 21} = frac{ 5 times 4 }{6 times 3} = frac{5 times 2}{3 times 3} = frac{10}{9} = 1 frac{1}{9}$

$1 frac{7}{25} div 6 frac{2}{5} = frac{32}{25} div frac{32}{5} = frac{32 times 5}{25 times 32} = frac{1}{5} \ frac{5}{38} div 5 = frac{5}{38} times frac{1}{5} = frac{1}{38} \ frac{18}{23} div 6 = frac{18}{23} times frac{1}{6} = frac{3}{23}$

$5 frac{1}{3} div 6 frac{2}{3} = frac{16}{3} div frac{20}{3} = frac{16 times 3}{3 times 20} = frac{4}{5} \ 4.2 div 3 frac{1}{2} = frac{42}{10} div frac{7}{2} = frac{42 times 2}{10 times 7} = frac{6}{5} = 1 frac{1}{5} = 1.2 \ 5.7 div 6 frac{1}{3} = frac{57}{10} div frac{19}{3} = frac{57 times 3}{10 times 19} = frac{9}{10} = 0.9$

$frac{8}{11} div 0.4 = frac{8}{11} div frac{4}{10} = frac{8 times 10}{11 times 4} = frac{20}{11} = 1 frac{9}{11} \ 2.2 div 11.15 = frac{22}{10} div frac{1115}{100} = frac{22 times 100}{10 times 1115} = frac{22 times 2}{223} = frac{44}{223} \ 5 frac{1}{7} div 3 frac{3}{14} = frac{36}{7} div frac{45}{14} = frac{36 times 14}{7 times 45} = frac{4 times 2}{5} = frac{8}{5} = 1 frac{3}{5}$

$8 div 2 frac{2}{3} = 8 div frac{8}{3} = 8 times frac{3}{8} = 3 \ 1 frac{1}{3} div 1 frac{7}{9} = frac{4}{3} div frac{16}{9} = frac{4 times 9}{3 times 16} = frac{3}{4} \ frac{15}{16} div frac{5}{6} = frac{15 times 6}{16 times 5} = frac{3 times 3}{8} = frac{9}{8} = 1 frac{1}{8}$

$frac{4 frac{1}{3} div 6.5 }{2 frac{1}{6} div 3.25 } = frac{ frac{13}{3} div frac{65}{10} }{ frac{13}{6} div frac{325}{100} } = frac{ frac{13 times 10}{3 times 65} }{ frac{13 times 100}{6 times 325} } = frac{13 times 10 times 6 times 325}{3 times 65 times 13 times 100} = frac{6 times 325}{3 times 65 times 10} = frac{2 times 5}{10} = frac{10}{10} = 1$

$frac{7 frac{7}{8} div 1.5}{2 frac{2}{5} div 1 frac{1}{7} } = frac{ frac{63 times 10}{8 times 15} }{ frac{12 times 7}{5 times 8} } = frac{63 times 10 times 5 times 8}{8 times 15 times 12 times 7} = frac{9 times 10}{3 times 12} = frac{3 times 5}{6} = frac{5}{2} = 2 frac{1}{2} = 2.5$
