Пошаговое объяснение:

№1

$\frac{14}{93}$+5 = 5$\frac{14}{93}$

6$\frac{17}{41}$+7$\frac{19}{41}$=$(6+7)\frac{17+19}{41}$=$13\frac{36}{41}$

(24-17)$\frac{9-5}{38}$=$7\frac{4}{38}$

(7+2)$\frac{14+1}{15}$=9$\frac{15}{15}$=10

(9+12)$\frac{24+13}{27}$=$21\frac{37}{27}$=$22\frac{10}{27}$

$1- \frac{12}{19}$=$\frac{19}{19} -\frac{12}{19}$=$\frac{7}{19}$

$8-3\frac{6}{15} = 7\frac{15}{15}-3\frac{6}{15} = 4\frac{9}{15}$

$16\frac{3}{13} -6\frac{8}{13} = 15\frac{16}{13} -6\frac{8}{13} = 9\frac{8}{13}$

№2

25-x=$8\frac{3}{14}$     $25-8\frac{3}{14}$=x   x=$24\frac{14}{14} -8\frac{3}{14}=16\frac{11}{14}$

$7\frac{7}{30} -(5\frac{11}{30}-y)=3\frac{19}{30}$     $7\frac{7}{30} -5\frac{11}{30}+y=3\frac{19}{30}$      $y=3\frac{19}{30}-7\frac{7}{30} + 5\frac{11}{30}$     $y=(3+5-7)\frac{19-7+11}{30}=1\frac{23}{30}$
