Answer 1

$\frac{(11.1 \div 3 - 2 \frac{1}{6} ) \div 1 \frac{2}{21} }{(3 \frac{5}{6} + 1.5) \times \frac{3}{4} } = 0.35 \\ 1) \: \: 11.1 \div 3 = 3.7 = 3 \frac{7}{10} \\ 2)\: \: 3 \frac{7}{10} - 2 \frac{1}{6} = 3 \frac{21}{30} - 2 \frac{5}{30} = 1 \frac{16}{30} = 1 \frac{8}{15} \\ 3) \: \: 1 \frac{8}{15} \div 1 \frac{2}{21} = \frac{23 \times 21}{15 \times 23} = \frac{1 \times 7}{5 \times 1} = 1\frac{2}{5} = 1.4 \\ 4) \: \: 3 \frac{5}{6} + 1.5 = 3 \frac{5}{6} + 1 \frac{1}{2} = 3 \frac{5}{6} + 1 \frac{3}{6} = 4 \frac{8}{6} = 4 \frac{4}{3} = 5 \frac{1}{3} \\ 5) \: \: 5\frac{1}{3} \times \frac{3}{4} = \frac{16 \times 3}{3 \times 4} = \frac{4 \times 1}{1 \times 1} = 4 \\ 6) \: \: 1.4 \div 4 = \frac{1.4}{4} = \frac{14}{40} = \frac{7}{20} = 0.35$
