Question

1/3-2,5+1,1(6)
3-1,(3)+1/6
-2,(3)+16/3-6,(6)​

Answer 1

$1. \: \: \frac{1}{3} - 2.5 + 1.1(6) = \\ \frac{1}{3} - \frac{1}{4} + \frac{116 - 11}{90} = \\ \frac{4 - 3}{12} + \frac{105}{90} = \\ \frac{1}{12} + \frac{21}{18} = \\ \frac{1}{12} + \frac{7}{6} = \\ \frac{1 + 14}{12} = \\ \frac{15}{12} = \frac{5}{4} \\ \\ 2. \: \: 3 - 1.(3) + \frac{1}{6} = \\ \frac{3}{1} - \frac{12}{9} + \frac{1}{6} = \\ \frac{3 \times 6 - 12 \div 3 \times 2 + 1}{6} = \\ \frac{11}{6} \\ \\ 3. \: \: - 2.(3) + \frac{16}{3} - 6.(6) = \\ - \frac{21}{9} + \frac{16}{3} - \frac{60}{9} = \\ - \frac{7}{3} + \frac{16}{3} - \frac{20}{3} = \\ \frac{16 - 7 - 20}{3} = \\ \frac{11}{3}$
