Răspuns :

a)100cm-964mm+24cm=...mm

1000mm-964mm+240mm=36mm+240mm=276mm

b)72dm-450mm+249cm=...cm

720cm-45cm+249cm=675cm+259cm=934cm

c)1m-1dm-1cm-1mm=...mm

1000mm-100mm-10mm-1mm=889mm

d)74dam+1km+500m=...dam

74dam+100dam+50 dam=224dam

e)4km+2hm+15dam+279m=...m

4000m+200m+150m+279m=4629m

f)116km-2400dam-840hm+2000m=...dam

11600-2400dam-8400dam+200dam=1000dam

g)68.000m+27.500hm+4800dam-1998 km=...km

68km+2750+48-1998km=868km
