Answer 1

$19\frac{8}{9} - 8\frac{1}{9} =11\frac{7}{9} \\\\8\frac{3}{4} - 7\frac{3}{4} = 1\\\\3- 1 \frac{12}{13} = 3\frac{13}{13}- 1 \frac{12}{13}= 2 \frac{1}{13}\\\\4-2\frac{2}{3} = -3\frac{3}{3}-2\frac{2}{3}=1\frac{1}{3}\\\\17\frac{3}{8} - 8\frac{3}{8} = 9\\\\5\frac{7}{8} - 3 = 5\frac{7}{8} - 2\frac{8}{8} = 4\frac{15}{8} - 2\frac{8}{8} = 2\frac{7}{8}$
