Bună!

$(4,2: 0,012+3,5*0,24)*1,7 <=>\\<=> (\frac{42}{10} : \frac{12}{1000}+\frac{35}{10} *\frac{24}{100} )*\frac{17}{10} <=>$

$<=> (\frac{42}{10} *\frac{1000}{12} + \frac{7}{2}*\frac{6}{25} )*\frac{17}{110} <=>$

$<=> (7*\frac{100}{2}+7*\frac{3}{25})*\frac{17}{10} <=>$

$<=> (7*50+\frac{21}{25} )*\frac{17}{10} <=>$

$<=> (^{25)} 350+\frac{21}{25} )*\frac{17}{10} <=>$

$<=> \frac{8771}{25} *\frac{17}{10} =\frac{149107}{250} =596,428$
