Answer 1

$\frac{\left(6,829+\frac{14}{15}\cdot0,7-\left(5,629-\frac{14}{15}\cdot2,3\right)\right)-(-0,3)\cdot16\frac23}{-1,25:\left(-\frac5{12}\right)+6:3\frac{11}{13}+5,684:(-1,4)}\\1)\;\left(6,829+\frac{14}{15}\cdot0,7-\left(5,629-\frac{14}{15}\cdot2,3\right)\right)-(-0,3)\cdot16\frac23}=\\=\left(6,829+\frac{14}{15}\cdot0,7-5,629+\frac{14}{15}\cdot2,3\right)+0,3\cdot16\frac23=\\=6,829+\frac{14}{15}\cdot0,7-5,629+\frac{14}{15}\cdot2,3+\frac3{10}\cdot\frac{50}3=\\=1,2+\frac{14}{15}\cdot3+5=6,2+\frac{14}5=6,2+2,8=9$

$2)\;-1,25:\left(-\frac5{12}\right)+6:3\frac{11}{13}+5,684:(-1,4)=\\=1\frac14:\frac5{12}+6:\frac{50}{13}-\frac{5684}{1400}=\frac54\cdot\frac{12}5+6\cdot\frac{13}{50}-\frac{1421}{350}=\\=3+\frac{78}{50}-\frac{1421}{350}=\frac{1050+546-1421}{350}=\frac{175}{350}=\frac12\\\\3)\;9:\frac12=9\cdot2=18$
