$$4\frac{13}{17} + 5\frac{4}{17} = 9\frac{17}{17} = 10$$
$$3\frac{8}{11} + 2\frac{6}{11} = 5\frac{14}{11} = 6\frac{3}{11}$$
$$1 - \frac{16}{21} = \frac{21}{21} - \frac{16}{21} = \frac{5}{21}$$
$$5 - 2\frac{3}{8} = 4\frac{8}{8} - 2\frac{3}{8} = 2\frac{5}{8}$$
$$8\frac{4}{9} - 3\frac{7}{9} = 7\frac{13}{9} - 3\frac{7}{9} = 4\frac{6}{9} = 4\frac{2}{3}$$
$$12\frac{19}{44} - 6\frac{37}{44} = 11\frac{63}{44} - 6\frac{37}{44} = 5\frac{26}{44} = 5\frac{13}{22}$$
