 \frac{5}{8} - \frac{5}{9}  × 0,3= \frac{5}{8} - \frac{5}{9}  ×  \frac{3}{10}   \frac{5}{8} - \frac{1}{3} ×  \frac{1}{2}  \frac{5}{8}- \frac{1}{6} =  \frac{15}{24} - \frac{4}{24} = \frac{11}{24}
11/24 x (-1)= -11/24

 (\frac{1}{2}- \frac{1}{3} )^{2} :0,25=( \frac{3}{6}- \frac{2}{6})^{2} : \frac{25}{100} = (\frac{1}{6})^{2} × \frac{100}{25}=  \frac{1}{36} × \frac{100}{25}=   \frac{1}{9}  \frac{20}{25} =  \frac{1}{9} ×  \frac{4}{5}  =  \frac{4}{45}
acolo unde sunt A-urile pune semnul inmultirii
Ce inseamna Î si Ă ??
Ok . Ms mult !
