Question

In cate pungi se pot pune 45 de kg de faina,daca fiecare punga cantareste 5 kg

Answer 1

$1 \ punga=5 \ kg \\ x \ pungi=45 \ kg \\ \bold{Proportie:} \\ \frac{1 \ punga}{x \ pungi}=\frac{5 \ kg}{45 \ kg}= \frac{1 \ kg}{9 \ kg} \\ x \ pungi=9 \ kg \cdot 1 \\ \Rightarrow \boxed{45 \ kg=9 \ pungi}$
