Accepted Answer

$7\frac{9}{16}+8\frac{7}{16}=15\frac{16}{16}=16$.
$4\frac{9}{19}+5\frac{13}{19}=9\frac{22}{19}=10\frac{3}{19}$.
$1-\frac{16}{25}=\frac{25}{25}-\frac{16}{25}=\frac{9}{25}$.
$4-1\frac{7}{12}=3-\frac{7}{12}=2\frac{5}{12}$.
$6\frac{5}{14}-2\frac{11}{14}=5\frac{19}{14}-2\frac{11}{14}=3\frac{8}{14}=3\frac{4}{7}$.
$19\frac{11}{35}-12\frac{29}{35}=18\frac{46}{35}-12\frac{29}{35}=6\frac{17}{35}$.

Ответ: 1) 16; 2) $10\frac{3}{19}$; 3) $\frac{9}{25}$; 4) $2\frac{5}{12}$; 5) $3\frac{4}{7}$; 6) $6\frac{17}{35}$.

Вычислите: 1) \(7\frac{9}{16}+8\frac{7}{16}\); 2) \(4\frac{9}{19}+5\frac{13}{19}\); 3) \(1-\frac{16}{25}\); 4) \(4-1\frac{7}{12}\); 5) \(6\frac{5}{14}-2\frac{11}{14}\); 6) \(19\frac{11}{35}-12\frac{29}{35}\).
