Multiplii: decametru(dam), hectometru(hm), kilometru(km)
10,2km=1020dam
24dam2=240m2, 0,3hm2=3000m2
10m2+240m2+3000m2=3250m2
72dam=720m, 14278cm=142,28m, 0,25km=250m
720m+142,28m+250m+4,25m=1117,03m
incerc :D
ok, te rog mult :)
1/2+1(intreg)16-1/90+1(intreg)13/10:6/9(care simplificat prin 3 devine 2/3 iar 2/3 la puterea a 2 a 4/9)=
apoi raman doar calcule
ce inseamnă .. / ...? impărțit?
da impartire adica 1supra 2
