Answer 5

$1)2 times frac{2}{3} times frac{9}{32} times 5 frac{1}{3} = 2 \ \ 1)2 times frac{2}{3} = frac{2 times 2}{3} = frac{4}{3} = 1 frac{1}{3} \ \ 2)1 frac{1}{3} times frac{9}{32} = frac{4}{3} times frac{9}{32} = frac{4 times 9}{3 times 32} = frac{1 times 3}{1 times 8} = frac{3}{8} \ \ 3) frac{3}{8} times 5 frac{1}{3} = frac{3}{8} times frac{16}{3} = frac{3 times 16}{8 times 3} = frac{1 times 2}{1 times 1} = frac{2}{1} = 2$


$2)6 frac{1}{4} times 1 frac{1}{35} times 2 frac{1}{3} = frac{5}{12} \ \ 1)6 frac{1}{4} times frac{1}{35} = frac{25}{4} times frac{1}{35} = frac{25 times 1}{4 times 35} = frac{5 times 1}{4 times 7} = frac{5}{28} \ \ 2) frac{5}{28} times 2 frac{1}{3} = frac{5}{28} times frac{7}{3} = frac{5 times 7}{28 times 3} = frac{5 times 1}{4 times 3} = frac{5}{12}$



$3) frac{18}{25} times frac{10}{27} times 7 frac{1}{2} = 2 \ \ 1) frac{18}{25} times frac{10}{27} = frac{18 times 10}{25 times 27} = frac{2 times 2}{5 times 3} = frac{4}{15} \ \ 2) frac{4}{15} times 7frac{1}{2} = frac{4}{15} times frac{15}{2} = frac{4 times 15}{15 times 2} = frac{2 times 1}{1 times 1} = frac{2}{1} = 2$



$4)12 frac{6}{7} times frac{2}{25} times frac{7}{18} = frac{2}{5} \ \ 1)12 frac{6}{7} times frac{2}{25} = frac{90}{7} times frac{2}{25} = frac{90 times 2}{7 times 25} = frac{18 times 2}{7 times 5} = frac{36}{35} = 1 frac{1}{35} \ \ 2)1 frac{1}{35} times frac{7}{18} = frac{36}{35} times frac{7}{18} = frac{36 times 7}{35 times 18} = frac{2 times 1}{5 times 1} = frac{2}{5}$




$5)8 frac{1}{3} times 2 frac{1}{5} times 1frac{1}{11} = 22 frac{8}{11} \ \ 1)8 frac{1}{3} times 2 frac{1}{2} = frac{25}{3} times frac{5}{2} = frac{25 times 5}{3 times 2} = frac{125}{6} = 20 frac{5}{6} \ \ 2)20 frac{5}{6} times 1frac{1}{11} = frac{125}{6} times frac{12}{11} = frac{125 times 12}{6 times 11} = frac{125 times 2}{1 times 11} = frac{250}{11} = 22 frac{8}{11}$
