[tex]\frac{3}{7} =\frac{5}{9} =>3*9=7*5=>27\neq 35\\\frac{44}{21}=\frac{11}{\frac{21}{4} } =>\frac{44}{21}=\frac{11*4}{21} =>44*21=21*44=>924=924 \\\\\frac{\frac{5}{2} +3}{\frac{5}{6}}=\frac{\frac{3}{9} *\frac{6}{5} }{4} =>\frac{\frac{11}{2} }{\frac{5}{6} } =\frac{\frac{2}{5} }{4} =>\frac{11}{2}*\frac{6}{5} =\frac{2}{5}*4 =>\frac{33}{5} = \frac{8}{5}=>33*5=8*5=>165\neq 40[/tex]
