$1); ; 2frac{3}{8}=2+frac{3}{8}=1+1+frac{3}{8}=1+frac{8}{8}+frac{3}{8}=1+frac{11}{8}\\3frac{5}{9}=2+1+frac{5}{9}=2+frac{9}{9}+frac{5}{9}=2+frac{14}{9}=2frac{14}{9}\\4frac{1}{11}=3+1+frac{1}{11}=3+frac{11}{11}+frac{1}{11}=3+frac{12}{11}=3frac{12}{11}\\5frac{7}{10}=4+1+frac{7}{10}=4+frac{10}{10}+frac{7}{10}=4+frac{17}{10}=4frac{17}{10}$

$3frac{2}{3}=2+frac{3}{3}+frac{2}{3}=2+frac{5}{3}=2frac{5}{3}\\6frac{1}{6}=5+frac{6}{6}+frac{1}{6}=5+frac{7}{6}=5frac{7}{6}\\10frac{4}{13}=9+frac{13}{13}+frac{4}{13}=9+frac{17}{13}=9frac{17}{13}\\4frac{5}{12}=3+frac{12}{12}+frac{5}{12}=3+frac{17}{12}=3frac{17}{12}$

$1frac{11}{100}=frac{100}{100}+frac{11}{100}=frac{111}{100}\\2frac{3}{13}=1+frac{16}{13}=1frac{16}{13}\\13frac{3}{5}=12frac{8}{5}; ; ,; ; 7frac{6}{7}=6frac{13}{7}; ; ,; ; 8frac{10}{21}=7frac{31}{21} ; ; ,; ; 11frac{1}{5}=10frac{6}{5}; ; ,; ; 5frac{11}{14}=4frac{25}{14}; ; ,\\3frac{17}{25}=2frac{42}{25}; ; ,; ; 16frac{9}{10}=15frac{19}{10}; ; ,; ; 20frac{4}{51}=19frac{55}{51}\\\2); ; 3frac{20}{17}=3+frac{17+3}{17}=3+frac{17}{17}+frac{3}{17}=3+1+frac{3}{17}=4+frac{3}{17}=4frac{3}{17}$

$2frac{5}{3}=2+frac{3+2}{3}=2+frac{3}{3}+frac{2}{3}=2+1+frac{2}{3}=3+frac{2}{3}=3frac{2}{3}\\14frac{17}{15}=14+frac{15+2}{15}=14+frac{15}{15}+frac{2}{15}=14+1+frac{2}{15}=15frac{2}{15}\\1frac{18}{13}=1+frac{13}{13}+frac{5}{13}=1+1+frac{5}{13}=2frac{5}{13}\\7frac{9}{7}=7+frac{7}{7}+frac{2}{7}=7+1+frac{2}{7}=8frac{2}{7}\\5frac{13}{10}=5+frac{10}{10}+frac{3}{10}=5+1+frac{3}{10}=6frac{3}{10}$

$2frac{19}{11}=2+frac{11}{11}+frac{8}{11}=3frac{8}{11}\\4frac{11}{6}=4+frac{6}{6}+frac{5}{6}=5frac{5}{6}\\6frac{17}{9}=6+frac{9}{9}+frac{8}{9}=7frac{8}{9}\\3frac{14}{11}=4frac{3}{11}; ; ,; ; 8frac{7}{5}=9frac{2}{5}; ; ,; ; 13frac{5}{4}=14frac{1}{4}; ; ,; ; 1frac{19}{12}=2frac{7}{12}; ; ,; ; 2frac{27}{14}=3frac{13}{14}; ; ,$
