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

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