Question

[tex]frac{1}{3} +(10,66:2frac{3}{5}+1frac{1}{5}-0,3):3

Answer 1

$frac{1}{3} + (10frac{66}{100} : 2frac{3}{5} + 1frac{1}{5} - 0,3) : 3 =$

1) $10frac{66}{100} : 2frac{3}{5} = frac{1066}{100} : frac{13}{5} = frac{1066}{100} * frac{5}{13} = frac{82}{20} = 4frac{2}{20} = 4,1$

2) $frac{82}{20} + frac{6}{5} = frac{82}{20} + frac{24}{20} = frac{106}{20} = 5frac{6}{20} = 5,3$

3) 5,3 - 0,3 = 5

4) 5 : 3 ≈ 1,6

5) $frac{1}{3} + 1frac{6}{10} = frac{1}{3} + frac{16}{10} = frac{10}{30} + frac{48}{30} = frac{58}{30} = 1frac{28}{30} = 1,93$
