Question

efectuiaza:a)5dam+60dm=............m b)52hm+3200cm=..........m c)85dam:50dm=........m d)32hm*300cm=.....m

Answer 1

a) 5dam= 50 m

60 dm= 6 m

50+6=55 m

b) 52 hm= 520 dam= 5200 m

3200 cm= 320dm= 32 m

5200+32= 5232 m

c) 85 dam= 8,5 m

50dm= 5m

8,5:5= 1,7 m

d)32 hm= 320 dam= 3200 m

300 cm= 30 dm= 3 m

3200*3= 9600 m

Answer 2

a)5dam + 60dm = 56m
5dam = 50 m
60dm = 6 m
50m+6m=56m

b) 52 hm + 3200cm = 5232m
52hm = 5200m
3200cm = 32m
5200m+32m= 5232m

c) 85dam :50dm =1700m
85dam=8500m
50dm = 5m
8500m:5m = 1700m

d)32hm * 300cm = 9600m
32hm= 3200m
300cm=3m
3200m*3m= 9600m

Succes!
