espero ter ajudado fofo  ✌️

14/14 - 3/14 - 1/5 =41\70

$\frac{14}{14}-\frac{3}{14}-\frac{1}{5}=\frac{41}{70}\quad \left(\mathrm{Decimal:\quad }\:0.58571\dots \right)\\\\\frac{14}{14}-\frac{3}{14}-\frac{1}{5}\\\\\frac{14}{14}=1\\\\\frac{14}{14}\\\\1\\1=\frac{14\cdot \:1}{14}\\\\\frac{14\cdot \:1}{14}\\\\\frac{14\cdot \:1}{14}-\frac{3}{14}-\frac{1}{5}\\\\\frac{14}{14}-\frac{3}{14}-\frac{1}{5}\\\\\\\frac{14-3}{14}-\frac{1}{5}\\\\\frac{11}{14}-\frac{1}{5}\\\\\mathrm{MInimo\:multiplo\:comum\:de\:}14,\:5:\quad 70\\\\2\cdot \:7$

$14=7\cdot \:2\\2\cdot \:7\cdot \:5\\70\\\frac{55}{70}-\frac{14}{70}=\frac{55-14}{70}\\\frac{41}{70}$
