Question

-2/3-1/4+2/6 como resolver essa fração

Answer 1

$\boxed{\begin{array}{l}\sf-\dfrac{2}{3}-\dfrac{1}{4}+\dfrac{2}{6}\\\\\begin{array}{l|l}\sf3,4,6&\sf2\\\sf3,2,3&\sf2\\\sf3,1,3&\sf3\\\sf1,1,1,\end{array}\\\sf mmc (3,4,6)=2\cdot2\cdot3=12\\\sf escrevendo\,frac_{\!\!,}\tilde oes\,equivalentes\\\sf com\,denominador\,12\,temos:\\\sf-\dfrac{2}{3}-\dfrac{1}{4}+\dfrac{2}{6}=-\dfrac{8}{12}-\dfrac{3}{12}+\dfrac{4}{12}\\\\\sf-\dfrac{2}{3}-\dfrac{1}{4}+\dfrac{2}{6}=\dfrac{-8-3+4}{12}=-\dfrac{7}{12}\end{array}}$
