Объяснение:

$1)\ \frac{x}{3}=\frac{9,6}{14,4} \\x=\frac{3*9,6}{14,4}=\frac{9,6}{4,8}=2.\\2)\ \frac{x}{4}=\frac{49,5}{66}\\x=\frac{49,5*4}{66} =\frac{49,5*2}{33} =\frac{99}{33}=3.\\3)\ \frac{6,5}{x} =\frac{104}{144}\\ x=\frac{144*6,5}{104} =\frac{72*6,5}{52}=\frac{72}{8}=9.\\4)\ \frac{16,1}{25,3} =\frac{x}{16,5} \\x=\frac{16,5*16,1}{25,3} =\frac{11*1,5*16,1}{11*2,3} =\frac{1,5*16.1}{2,3}=1,5*7=10,5.$

$5)\ \frac{3\frac{3}{7} }{|-7\frac{3}{7}| } =\frac{y}{13} \\\frac{\frac{24}{7} }{\frac{52}{7} } =\frac{y}{13}\\\frac{6}{13}=\frac{y}{13}\\y=6.\\6)\ \frac{9}{y}=\frac{|-4\frac{1}{11}| }{|-7\frac{3}{11}| } \\\frac{9}{y} =\frac{\frac{45}{11} }{\frac{75}{11} } \\\frac{9}{y} =\frac{9}{15} \\y=15.\\7)\ \frac{|23|}{y}=\frac{|-3\frac{37}{49}| }{4\frac{4}{49} }\\\frac{23}{y}=\frac{\frac{184}{49} }{\frac{200}{49} } \\\frac{23}{y}=\frac{23}{25}\\y=25.$

$8)\ \frac{y}{16}=\frac{|76,25|}{|-1\frac{5}{56}| } \\\frac{y}{16}=\frac{76\frac{1}{4} }{1\frac{5}{56} } \\\frac{y}{16}=\frac{\frac{305}{4} }{\frac{61}{56} } \\\frac{y}{16}=\frac{5}{14}\\y=\frac{5*16}{14}=\frac{40}{7}=5\frac{5}{7} .$
