Answer 1

$1,7+( \frac{2}{3} -0,25)- \frac{1}{4} = \\ \\ = \frac{17}{10} +( \frac{2}{3} - \frac{25}{100} )- \frac{1}{4} = \\ \\ = \frac{17}{10} +( \frac{2}{3} - \frac{1}{4} )- \frac{1}{4} = \\ \\ = \frac{17}{10} +( \frac{4.2-3.1}{12} )- \frac{1}{4} = \\ \\ = \frac{17}{10} +( \frac{8-3}{12})- \frac{1}{4} = \\ \\ =\frac{17}{10} + \frac{5}{12} - \frac{1}{4} = \\ \\ = \frac{6.17+5.5-15}{60} = \\ \\ = \frac{102+25-15}{60} = \\ \\ = \frac{112}{60} = \frac{28}{15} =1,866667$
