Szczegółowe wyjaśnienie:
=4/9×18/6+7/2:5/4=
=4/3+7/2×4/5=
=4/3+14/5=
=1 1/3+2 4/5=
=1 5/15+2 12/15=
=3 17/15=4 2/15
[tex]\frac{4}{9} :\frac{6}{18} +3 \frac{1}{2} :1\frac{1}{4} =\frac{4}{9} :\frac{6}{18} +\frac{7}{2} :\frac{5}{4} =\frac{4}{9} \cdot\frac{\not18}{\not6} +\frac{7}{\not2} \cdot\frac{\not4}{9} =\frac{4}{\not9} \cdot\not3+7\cdot\frac{2}{5} =[/tex]
[tex]=\frac{4}{3} +7\cdot\frac{2}{5} =\frac{4}{3} +\frac{14}{5} =1\frac{1}{3} +2\frac{4}{5} =1\frac{5}{15} +2\frac{12}{15} =3\frac{17}{15} =4\frac{2}{15}[/tex]
