(23/6-11/4)×12/7+11/2=13/12×12/7+11/2=13/12×12/7+11/2= 13×1/7+11/2=13/7+11/2=103/14

Answer 2

Ответ:

Пошаговое объяснение:

$3\frac{5}{6} -2\frac{3}{4} =\frac{23}{6} -\frac{11}{4} =\frac{23*2-11*3}{12} =\frac{13}{12}$

$\frac{13}{12} :\frac{7}{12} =\frac{13}{12}*\frac{12}{7} =\frac{13}{7}$

$\frac{13}{7} +\frac{11}{2} =\frac{13*2+11*7}{14} =\frac{26+77}{14} =\frac{103}{14} =7\frac{5}{14}$
