Ответ:

а)5/8+17/24=15/24+17/24=32/24=4/3=1 1/3

б)8/25 - 3/20=32/100 - 15/100=17/100

в)9 3/7 + 7 5/6=9 18/42 + 7 35/42=17 11/42

Answer 2

а) $\frac{5}{8}$ + $\frac{17}{24}$ = $\frac{15}{24}$ + $\frac{17}{24}$ = $\frac{32}{24}$ = $\frac{4}{3}$ = 1 $\frac{1}{3}$

б) $\frac{8}{25}$ - $\frac{3}{20}$ = $\frac{32}{100}$ - $\frac{15}{100}$ = $\frac{17}{100}$ = 0,17

в) 9 $\frac{3}{7}$ + 7 $\frac{5}{6}$ = $\frac{66}{7}$ + $\frac{47}{6}$ = $\frac{396}{42}$ + $\frac{329}{42}$ = $\frac{725}{42}$ = 17 $\frac{11}{42}$
