Answer 1

Ответ:

1) $5\frac{1}{3}$ ; 2) $13\frac{29}{35}$ ; 3) $11\frac{5}{8}$ ; 4) $4\frac{5}{24}$ ; 5) $7\frac{13}{15}$ ; 6) $12\frac{7}{8}$ .

Пошаговое объяснение:

1) $3\frac{1}{2}+1\frac{5}{6} =(3+1)+(\frac{1}{2} + \frac{5}{6}) = 4 + \frac{4}{3} = 4+1\frac{1}{3} = 4+1+\frac{1}{3} = 5+\frac{1}{3} = 5\frac{1}{3}$

2) $4\frac{2}{5} + 9\frac{3}{7} = (4+9) + (\frac{2}{5} + \frac{3}{7}) = 13 + \frac{29}{35} = 13\frac{29}{35}$

3) $8\frac{3}{4} + 2\frac{7}{8} = (8+2)+(\frac{3}{4}+\frac{7}{8}) = 10+\frac{13}{8} = 10+1\frac{5}{8} = 10+1+\frac{5}{8} = 11+\frac{5}{8} = 11\frac{5}{8}$

4) $2\frac{3}{8} + 1\frac{5}{6} = (2+1) + (\frac{3}{8}+\frac{5}{6}) = 3+\frac{29}{24} = 3+1\frac{5}{24} = 3+1+\frac{5}{24} = 4 + \frac{5}{24} = 4\frac{5}{24}$

5) $6\frac{1}{5} + 1\frac{2}{3} = (6+1)+(\frac{1}{5} + \frac{2}{3}) = 7+\frac{13}{15} = 7\frac{13}{15}$

6) $4\frac{3}{8} + 8\frac{1}{2} = (4+8)+(\frac{3}{8} + \frac{1}{2}) = 12 + \frac{7}{8} = 12\frac{7}{8}$
