Question

Вычислите: 1/4+7/12+1 целая 1/3 - (1 целая1/6 - 1/2)Срочно

Answer 1

$frac{1}{4} + frac{7}{12} +1 frac{1}{3} - (1 frac{1}{6} - frac{1}{2} )= 1 frac{1}{2} \\\\ textgreater 1 frac{1}{6} - frac{1}{2} = frac{7}{6} - frac{1}{2} = frac{7}{6} - frac{3}{6} = frac{4}{6} = frac{2}{3} \\ textgreater frac{1}{4} + frac{7}{12} = frac{3}{12} + frac{7}{12}= frac{10}{12}= frac{5}{6}\\ textgreater frac{5}{6}+1 frac{1}{3} - frac{2}{3} = frac{5}{6}+ frac{4}{3} - frac{2}{3}=frac{5}{6} + frac{2}{3}=frac{5}{6}+frac{4}{6}=frac{9}{6}=frac{3}{2}=1 frac{1}{2}$
