Выдели целую часть из неправильной дроби в номере 4

Конечно, помогу! Вот ответы: 4) $1\frac{18}{13} = \frac{1 \cdot 13 + 18}{13} = \frac{31}{13} = 2\frac{5}{13}$ 5) $7\frac{9}{7} = \frac{7 \cdot 7 + 9}{7} = \frac{58}{7} = 8\frac{2}{7}$ 6) $5\frac{13}{10} = \frac{5 \cdot 10 + 13}{10} = \frac{63}{10} = 6\frac{3}{10}$ 7) $2\frac{19}{11} = \frac{2 \cdot 11 + 19}{11} = \frac{41}{11} = 3\frac{8}{11}$ 8) $4\frac{11}{6} = \frac{4 \cdot 6 + 11}{6} = \frac{35}{6} = 5\frac{5}{6}$ 9) $6\frac{17}{9} = \frac{6 \cdot 9 + 17}{9} = \frac{71}{9} = 7\frac{8}{9}$ 10) $3\frac{14}{11} = \frac{3 \cdot 11 + 14}{11} = \frac{47}{11} = 4\frac{3}{11}$ 11) $8\frac{7}{5} = \frac{8 \cdot 5 + 7}{5} = \frac{47}{5} = 9\frac{2}{5}$ 12) $13\frac{5}{4} = \frac{13 \cdot 4 + 5}{4} = \frac{57}{4} = 14\frac{1}{4}$ 13) $1\frac{19}{12} = \frac{1 \cdot 12 + 19}{12} = \frac{31}{12} = 2\frac{7}{12}$ 14) $2\frac{27}{14} = \frac{2 \cdot 14 + 27}{14} = \frac{55}{14} = 3\frac{13}{14}$ 15) $6\frac{15}{8} = \frac{6 \cdot 8 + 15}{8} = \frac{63}{8} = 7\frac{7}{8}$ 16) $5\frac{29}{16} = \frac{5 \cdot 16 + 29}{16} = \frac{109}{16} = 6\frac{13}{16}$ 17) $4\frac{39}{27} = \frac{4 \cdot 27 + 39}{27} = \frac{147}{27} = 5\frac{12}{27} = 5\frac{4}{9}$ 18) $8\frac{100}{53} = \frac{8 \cdot 53 + 100}{53} = \frac{524}{53} = 9\frac{47}{53}$
