$\frac{3}{19} = \frac{6}{38}$; $\frac{15}{4} =\frac{30}{8}$; $\frac{14}{15} =\frac{28}{30}$; $\frac{23}{45} =\frac{46}{90}$;$\frac{3}{25} =\frac{6}{50}$

$\frac{8}{9} =\frac{24}{27}$; $\frac{2}{5} = \frac{6}{15}$; $\frac{4}{1} =\frac{12}{3}$;$\frac{11}{15} =\frac{33}{45}$;$\frac{24}{7} =\frac{72}{21}$

$\frac{31}{5} =\frac{124}{20}$;$\frac{24}{25} =\frac{96}{100}$;$\frac{27}{20} =\frac{107}{80}$;$\frac{29}{51} =\frac{116}{204}$;$\frac{72}{34} =\frac{288}{136}$

$\frac{12}{3} =\frac{60}{15}$;$\frac{17}{4} =\frac{85}{20}$;$\frac{31}{20} =\frac{155}{100} ;\frac{72}{8} =\frac{360}{40} ;\frac{9}{7} =\frac{45}{35}$
