Решите пожалуйста!! Не просто ответ,а полный ответ)

Answer 1

Номер 1.


1)
$4 \frac{7}{8} + 5 \frac{4}{7} = 4 \frac{49}{56} + 5 \frac{32}{56} = 9 \frac{81}{56} = 10 \frac{25}{56}$

2)
$6 \frac{7}{9} + 5 \frac{5}{12} = 6 \frac{28}{36} + 5 \frac{15}{36} = 11 \frac{43}{36} = 12 \frac{7}{36}$

3)
$7 \frac{3}{5} + 4 \frac{3}{4} = 7.6 + 4.75 = 12.35$

4)
$8 \frac{9}{11} + 4 \frac{7}{8} = 8 \frac{72}{88} + 4 \frac{77}{88} = 12 \frac{149}{88} = 13 \frac{61}{88}$

5)
$9 \frac{2}{5} - 5 \frac{4}{15} = 9 \frac{6}{16} - 5 \frac{4}{15} = 4 \frac{2}{15}$

6)
$7 \frac{1}{8} - 5 \frac{7}{16} =6 \frac{18}{16} - 5 \frac{7}{16} = 1 \frac{11}{16}$

7)
$8 \frac{3}{10} - 7 \frac{7}{15} = 7 \frac{39}{30} - 7 \frac{14}{30} = \frac{25}{30} = \frac{5}{6}$

8)
$9 \frac{2}{9} - 6 \frac{5}{11} =8 \frac{121}{99} - 6 \frac{45}{99} = 2 \frac{76}{99}$

9)
$6 - 2 \frac{5}{6} = 3 \frac{1}{6}$

10)
$7 - \frac{5}{7} = 6 \frac{2}{7}$

11)
$12 + \frac{2}{3} = 12 \frac{2}{3}$

Номер 2.

1)
$\frac{3}{10} \times \frac{8}{9} = \frac{4}{15}$

2)
$\frac{22}{1} \times \frac{5}{33} = \frac{10}{3} = 3 \frac{1}{3}$

3)
$\frac{19}{7} \times \frac{35}{1} = 95$

4)
$\frac{13}{2} \times \frac{33}{16} = \frac{429}{38} = 11 \frac{11}{38}$
или

$6 \frac{8}{16} - 2 \frac{1}{16} = 4 \frac{7}{16}$

5)
$4 \frac{8}{6} - 3 \frac{5}{6} = 1 \frac{3}{6} = 1 \frac{1}{2} = 1.5$
или

$\frac{16}{3} \times \frac{23}{6} = \frac{368}{18} = 20 \frac{4}{9}$
