Question

determine o valor da expresao 1/3-(-1/2+3/4)+(-1+5/3)

Answer 1

$\frac{1}{3} -( \frac{-1}{2} + \frac{3}{4} )+(-1+ \frac{5}{3} )= \frac{1}{3} -( \frac{-2+3}{4} )+ (\frac{-3+5}{3} )=  \frac{1}{3} - \frac{1}{4} + \frac{2}{3} =   \frac{4-3+8}{12} = \frac{9}{12}$



Espero ter ajudado,da um atualizar ai e veja a resposta :)

Answer 2

$\frac{1}{3} - (- \frac{1}{2}+ \frac{3}{4} )+ (- 1 +\frac{5}{3})\\ \\ \frac{1}{3}- ( \frac{-2+3}{4} ) + (\frac{-3+5}{3} )\\ \\ \frac{1}{3} - \frac{1}{4} + \frac{2}{3}\\ \\ \boxed{\frac{4-3+8}{12}= \frac{9}{12}= \frac{3}{4} }$
