Question

2sobre98+4sobre50-8sobre34 dividido 2sobre99-32sobre20+2sobre101 =

Answer 1

Seja $\text{X}=\left(\dfrac{2}{98}+\dfrac{4}{50}-\dfrac{8}{34}\right)\div\left(\dfrac{2}{99}-\dfrac{32}{20}+\dfrac{2}{101}\right)$

 

$\text{X}=\left(-\dfrac{2~809}{20~825}\right)\div\left(-\dfrac{39~322}{199~980}\right)$

 

$\text{X}=\left(-\dfrac{2~809}{20~825}\right)\cdot\left(-\dfrac{199~980}{39~322}\right)$

 

$\text{X}=\dfrac{561743820}{818880650}$
