Answer 1

Răspuns:

2. a) 500 dam = 5000m

       1000m-50dam=100dam-50dam=50dam

       6x250dam=1250dam=125hm

   

   b) 4m+32dm=40dm+32dm=72dm

       42m-30dm=420dm-32dm=388dm=38.8m

       6x220dm=1320=132m

   

    c) 17dm+19cm=170cm+19cm=189 cm

        415dm-70cm=415dm-7dm=408dm

        80mm:2=40mm=0.04m
