1) 4 $\frac{2}{3}$ - $\frac{2}{3}$ = $\frac{14}{3}$ - $\frac{2}{3}$ = $\frac{12}{3}$ =4

2) 9 $\frac{5}{9}$ - $\frac{5}{9}$ = $\frac{86}{9}$ - $\frac{5}{9}$ = $\frac{81}{9}$ =9

3) 25 $\frac{21}{31}$ - $\frac{21}{31}$ = $\frac{672}{31}$ - $\frac{21}{31}$ = $\frac{651}{31}$ =21

4) 75 $\frac{41}{69}$ - $\frac{41}{69}$ =.... (тут как и выше делаем)=75

5) 40 $\frac{5}{100}$ -11 $\frac{5}{100}$ = $\frac{4000}{100}$ - $\frac{1100}{100}$ = $\frac{2900}{100}$ =29

6) 8 $\frac{8}{7}$ -2 $\frac{2}{7}$ = $\frac{64}{7}$ - $\frac{16}{7}$ = $\frac{48}{7}$ =6 $\frac{6}{7}$

7) 20 $\frac{11}{13}$ -9 $\frac{2}{13}$ = $\frac{271}{13}$ - $\frac{119}{13}$ = $\frac{152}{13}$ =11 $\frac{9}{13}$

8) 10 $\frac{5}{17}$ -4 $\frac{3}{17}$ = $\frac{175}{17}$ - $\frac{71}{17}$ = $\frac{104}{10}$ =14 $\frac{6}{17}$

9) 19 $\frac{20}{29}$ -1 $\frac{17}{29}$ = $\frac{551}{29}$ - $\frac{46}{29}$ = $\frac{505}{29}$ =17 $\frac{22}{29}$

10) 83 $\frac{63}{101}$ -19 $\frac{24}{101}$ = $\frac{8446}{101}$ - $\frac{1919}{101}$ = $\frac{6527}{101}$ =64 $\frac{63}{101}$
