Question

Efectuati:(0,4+3supra 5):0.5

Answer 1

$\frac{0,4+3}{5} = \frac{ \frac{4}{10}simplificat cu 2 +3}{5} = \frac{ \frac{2}{5} +3}{5} = \frac{ \frac{17}{5} }{5} = \frac{17}{5} :5= \frac{17}{5} * \frac{1}{5} = \frac{17}{25}$
$0,5= \frac{5}{10} simplificat cu 5= \frac{1}{2}$
$\frac{17}{25} : \frac{1}{2} = \frac{17}{25} *2= \frac{34}{25}$

Answer 2

(0.4+3\5):0.5=
3\5=3:5=0.6
(0.4+0.6):0.5=1:0.5=2
