Answer 1

$1. \: \: \: 11.9 - 1 \frac{4}{5} \times 1 \frac{1}{3} = \frac{113}{10} = 11 \frac{3}{10} = 11.3$

$2. \: \: \: 16 \frac{1}{2} \div 11 + 9 \frac{1}{6} = \frac{32}{3} = 10 \frac{2}{3} = 10.6$

$3. \: \: \: (83.2 - 80 \frac{1}{6} ) \times \frac{3}{13} = \frac{7}{10} = 0.7$

$4. \: \: \: (0.28 + 1 \frac{1}{3} ) \div \frac{11}{30} = \frac{22}{5} = 4 \frac{2}{5} = 4.4$
