Question

Помогите алгебраааааааа​

Answer 1

Ответ:

$=\frac{28}{9} \div \frac{7}{1} - \frac{17}{6}$

Вот первое

Answer 2

$3\frac{1}{9} :2\frac{1}{3} -2\frac{5}{6} =\frac{28}{9} *\frac{3}{7} -\frac{17}{6} =\frac{4}{3} -\frac{17}{6}=\frac{8-17}{6} =-\frac{9}{6} =-\frac{3}{2}=-1,5$

$\frac{5}{12} +\frac{7}{14} =\frac{35+42}{84}=\frac{77}{84}$

$\frac{3}{16}+\frac{5}{12}=\frac{9+20}{48} =\frac{29}{48}$
