100de ani (definitie)
4*100cm=400cm=4m (400cm=(400:100) metri=4 metri)
3l=3000ml
3000ml:500ml=30:5=6sticle
6*250 g=1500g=(1500:1000) kg=1,5kg (am mutat virgula catre stanga cu 3 pozitii;care virgula? pai o pun eu, adica 1500=1500,0 si daca mut virgula catre stanga cu
3 pozitii cand impart la 1000, numarul devine 1,500=1,5)
Sper ca ti-am explicat ! (... :)))..)
