[tex]16 + \frac{4}{5} = 16 \frac{4}{5} = 16.8[/tex]

[tex]3 \frac{9}{16} + 2 \frac{7}{16} = 5 \frac{16}{16} = 6[/tex]

[tex]4 \frac{1}{15} - 2 \frac{4}{15} = 3 \frac{16}{15} - 2 \frac{4}{15} = \\ 1 \frac{12}{15} = 1 \frac{4}{5} = 1.8[/tex]

[tex]7 - \frac{9}{32} = 6 \frac{32}{32} - \frac{9}{32} = 6 \frac{23}{32} [/tex]
