Answer 1

$12\frac{2}{15}*3=\frac{182}{15}*3 =\frac{182}{15}*\frac{3}{1}=\frac{182}{5} *\frac{1}{1}=\frac{182}{5}= 36\frac{2}{5} \\\\\\9\frac{3}{10}*12=\frac{93}{10}*\frac{12}{1}=\frac{93}{5}*\frac{6}{1}=\frac{558}{5}= 111\frac{3}{5}\\\\\\5\frac{7}{15}*7=\frac{82}{15}*7=\frac{82}{15}*\frac{7}{1}=\frac{574}{15}=38\frac{4}{15}\\\\\\2\frac{3}{19}:41= \frac{41}{19}:41=\frac{41}{19} :\frac{41}{1}=\frac{41}{19}*\frac{1}\\{41}=\frac{1}{19}*\frac{1}{1}=\frac{1}{19}$

$15\frac{2}{3}:14=\frac{47}{3}:14=\frac{47}{3}:\frac{14}{1}=\frac{47}{3} *\frac{1}{14}=\frac{47}{42}=1\frac{5}{42}\\\\\\12\frac{1}{7}:25=\frac{85}{7}:25=\frac{85}{7}:\frac{25}{1}=\frac{85}{7} *\frac{1}{25}=\frac{17}{7}*\frac{1}{5} =\frac{17}{35}\\\\\\23\frac{1}{3}:5=\frac{70}{3}:5=\frac{70}{3}:\frac{5}{1}=\frac{70}{3}*\frac{1}{5}=\frac{14}{3}*\frac{1}{1}=\frac{14}{3}=4\frac{2}{3}$
