Scrie rezolvarea problemelor printr o expresie numerică si calculeaza:
a) Intr o parcare sunt 385 de autoturisme, iar motociclete de 11 ori mai putine,
Cate vehicule sunt in total in parcare?

Answer 1

Calculele le poti face pe calculator, iar la problema cu vehicule:
385 autoturisme
385:11(de 11 ori mai mic)=35 motociclete
=> nr vehicule= nr autoturisme+nr motociclete=385+35=420
