Question

(8 1/6 - 5/18):14/27 - (10 7/8 : 3/4 * 2/3 + 5 3/7 : 6 1/3)*3/17 пример

Answer 1

$left(8frac16 - frac5{18}right):frac{14}{27} - left(10frac78 : frac34 cdot frac23 + 5frac37 : 6frac13right)cdotfrac3{17}=\=left(frac{49}6-frac{5}{18}right)cdotfrac{27}{14}-left(frac{87}8cdotfrac43cdotfrac23+frac{38}7cdotfrac3{19}right)cdotfrac3{17}=\ =frac{142}{18}cdotfrac{27}{14}-left(frac{87}8cdotfrac89+frac{2cdot3}7right)cdotfrac3{17}=$
$=frac{71cdot3}{2cdot7}-left(frac{29}{3}+frac67right)cdotfrac3{17}=frac{213}{14}-frac{203+18}{21}cdotfrac3{17}=frac{213}{14}-frac{221}{21}cdotfrac3{17}=frac{213}{14}-frac{13}{7}=\=frac{213-26}{14}=frac{187}{14}=13frac5{14}$
