Answer 1

$1)5 \frac{2}{15} + 3 \frac{4}{15} = 8 \frac{2 + 4}{15} = 8 \frac{6}{15} = 8 \frac{2}{5}$

$2)9 \frac{5}{9} - 5 \frac{2}{9} = 4 \frac{5 - 2}{9} = 4 \frac{3}{9} = 4 \frac{1}{3}$

$3)4 \frac{1}{16} + \frac{5}{16} = 4 \frac{6}{16} = 4\frac{3}{8}$

$4)2 \frac{7}{15} + 1 \frac{8}{15} = 3 \frac{7 + 8}{15} = 3 \frac{15}{15} = 4$

$5) \frac{13}{21} + \frac{12}{21} = \frac{25}{21} = 1 \frac{4}{21}$
