Answer 1

$1 \frac{11}{14} + 2 \frac{5}{14} = 3 \frac{11 + 5}{14} = 3 \frac{16}{14} = 3 \frac{8}{7} = 4 \frac{1}{7}$

$8 - 5 \frac{7}{8} = 7 \frac{8}{8} - 5 \frac{7}{8} = 2 \frac{1}{8}$

$2 \frac{1}{9} -1 \frac{1}{3} = 2 \frac{1}{9} - 1\frac{3}{9} = 1 \frac{10}{9} - 1 \frac{3}{9} = \frac{7}{9}$

$1 \frac{4}{5} + 0.3 = 1 \frac{8}{10} + 0.3 = 1.8 + 0.3 = 2.1$

$3 \frac{1}{6} - 2 \frac{1}{12} = 3 \frac{2}{12} - 2 \frac{1}{12} = 1 \frac{1}{12}$
