a)Cati metri de materiale a cumparat in total ?
b)cu cati centimetri a cumparat mai multa catifea decat stofa ?

Answer 1

660 dm stofă = 66 m stofă
8 dam catifea = 80 m catifea
a.) Total material = 66 + 80 = 146 m
b.) Diferenţa de material = 80 - 66 = 14 m = 1400 cm

a) 660 dm = 66 m stofa
    8 dam = 80 m catifea
66 + 80 = 146 m materiale
b) 80 - 66 = 14 m = 1400 cm
