Выполните действия:
А) 5 8/15+4 7/12-3 19/20
Б) 20 7/18-(15 5/6-9 25/27
В) (36 2/3+3 1/8)-(18-10 5/9)

Answer 1

Ответ:

А = $6\frac{1}{6}$

Б = $4\frac{13}{27}$

В = $32\frac{25}{72}$

Пошаговое объяснение:

А) = $6\frac{1}{6}$

1) $5\frac{8}{15}$ + $4\frac{7}{12}$ = $10\frac{7}{60}$

2)  $10\frac{7}{60}$ - $3\frac{19}{20}$ = $6\frac{1}{6}$

Б) = $4\frac{13}{27}$

1) $20\frac{7}{18}$ - ($15\frac{5}{6}$ - $9\frac{25}{27}$) = $4\frac{13}{27}$

В) = $32\frac{25}{72}$

1) $36\frac{2}{3}$ + $3\frac{1}{8}$ = $39\frac{19}{24}$

2) 18 - $10\frac{5}{9}$ = $7\frac{4}{9}$

3) $39\frac{19}{24}$ - $7\frac{4}{9}$ = $32\frac{25}{72}$
