Question

-0,78*(-0,21)-0,22*(-0,21/4,8*1/3:(-0,016)=? Решите пожалуйста!срочно

Answer 1

$frac{ - 0.78 times ( - 0.21) - 0.22 times ( - 0.21)}{4.8 times frac{1}{3} div ( - 0.016)} = \ frac{( - 0.21)( - 0.78 - 0.22)}{1.6 div ( - 0.016)} = \ frac{( - 0.21) times ( - 1)}{ - 100} = \ frac{0.21}{ - 100} = - 0.0021$
