Chuyển các phân số 8 /5 ; 4/ 3 ; 9/ 7 ; 11 /5 ; 11 /6 ; 19/ 8 ; 7 /4 thành hỗn số:

\[\frac{8}{5} = \frac{{5 + 3}}{5} = \frac{5}{5} + \frac{3}{5} = 1 + \frac{3}{5} = 1\frac{3}{5}\]

\[\frac{4}{3} = \frac{{3 + 1}}{3} = \frac{3}{3} + \frac{1}{3} = 1 + \frac{1}{3} = 1\frac{1}{3}\]

\[\frac{9}{7} = \frac{{7 + 2}}{7} = \frac{7}{7} + \frac{2}{7} = 1 + \frac{2}{7} = 1\frac{2}{7}\]

\[\frac{{11}}{5} = \frac{{5 + 6}}{5} = \frac{5}{5} + \frac{6}{5} = 1 + \frac{6}{5} = 1\frac{6}{5}\]

\[\frac{{11}}{6} = \frac{{6 + 5}}{6} = \frac{6}{6} + \frac{5}{6} = 1 + \frac{5}{6} = 1\frac{5}{6}\]

\[\frac{{19}}{8} = \frac{{16 + 3}}{8} = \frac{{16}}{8} + \frac{3}{8} = 2 + \frac{3}{8} = 2\frac{3}{8}\]

\[\frac{7}{4} = \frac{{4 + 3}}{4} = \frac{4}{4} + \frac{3}{4} = 1 + \frac{3}{4} = 1\frac{3}{4}\]
