Question

4 2/3×(3 8/21)+(-8 5/6 - 4 4/5)÷3 3/10=

Answer 1

Ответ:

$4frac{2}{3} *(3frac{8}{21} ) + (-8frac{5}{6} - 4frac{4}{5} ) : 3frac{3}{10} = frac{14}{3} * frac{71}{21} + ((-8 - 4) + (-frac{5}{6} - frac{4}{5} )) : frac{33}{10} = frac{142}{9} - 12 frac{49}{30}: frac{33}{10}$

$= frac{142}{9} - frac{409}{30} * frac{10}{33} = frac{142}{9} - frac{409}{99} = frac{1562 - 409}{99} = frac{1153}{99}= 11frac{64}{99}$

Answer 4

Ответ:

Пошаговое объяснение:

$4frac{2}{3} *(3frac{8}{21} )+(-8frac{5}{6} -4frac{4}{5} ):3frac{3}{10} =\1)-8frac{5}{6} -4frac{4}{5} =-frac{53}{6} -frac{24}{5} =-frac{265}{30} -frac{144}{30}=-frac{409}{30} \2)4frac{2}{3} *3frac{8}{21}=frac{14}{3} *frac{71}{21} =frac{142}{9}\ 3)-frac{409}{30} :3frac{3}{10} =-frac{409}{30} :frac{33}{10} =-frac{409}{30} *frac{10}{33} =-frac{409}{99} \4)frac{142}{9} +(-frac{409}{99})=frac{1562}{99} -frac{409}{99} = frac{1153}{99} =11frac{64}{99}$
