Обратите смешанную дробь в обыкновенную дробь:
а) $5\frac{3}{8}$;
б) $9\frac{2}{3}$;
в) $4\frac{3}{5}$;
г) $7\frac{7}{10}$;
д) $5\frac{4}{5}$;
е) $13\frac{19}{20}$;
ж) $8\frac{9}{10}$;
з) $7\frac{1}{100}$;
и) $16\frac{12}{17}$;
к) $17\frac{5}{6}$;
л) $19\frac{99}{100}$;
м) $7\frac{357}{1000}$.
$5\frac{3}{8} = \frac{5 * 8 + 3}{8} = \frac{40 + 3}{8} = \frac{43}{8}$
$9\frac{2}{3} = \frac{9 * 3 + 2}{3} = \frac{27 + 2}{3} = \frac{29}{3}$
$4\frac{3}{5} = \frac{4 * 5 + 3}{5} = \frac{20 + 3}{5} = \frac{23}{5}$
$7\frac{7}{10} = \frac{7 * 10 + 7}{10} = \frac{70 + 7}{10} = \frac{77}{10}$
$5\frac{4}{5} = \frac{5 * 5 + 4}{5} = \frac{25 + 4}{5} = \frac{29}{5}$
$13\frac{19}{20} = \frac{13 * 20 + 19}{20} = \frac{260 + 19}{20} = \frac{279}{20}$
$8\frac{9}{10} = \frac{8 * 10 + 9}{10} = \frac{80 + 9}{10} = \frac{89}{10}$
$7\frac{1}{100} = \frac{7 * 100 + 1}{100} = \frac{700 + 1}{100} = \frac{701}{100}$
$16\frac{12}{17} = \frac{16 * 17 + 12}{17} = \frac{272 + 12}{17} = \frac{284}{17}$
$17\frac{5}{6} = \frac{17 * 6 + 5}{6} = \frac{102 + 5}{6} = \frac{107}{6}$
$19\frac{99}{100} = \frac{19 * 100 + 99}{100} = \frac{1900 + 99}{100} = \frac{1999}{100}$
$7\frac{357}{1000} = \frac{7 * 1000 + 357}{1000} = \frac{7000 + 357}{1000} = \frac{7357}{1000}$
