Rezolvați :240dam+15hm+1,2km=? 15hm+1,2km+1350m=? ​

Answer 1

Răspuns:

Explicație pas cu pas:

240 dam + 15 hm + 1,2 km = ?

240 dam = 2400 m

15 hm = 1500 m

1,2 km = 1200 m

240 dam + 15 hm + 1,2 km =

= 2400 m + 1500 m + 1200 m = 5100 m =

= 5100 m = 510 dam = 51 hm = 5,1 km

15 hm + 1,2 km + 1350 m = ?

15 hm = 1500 m

1,2 km = 1200 m

1350 m = 1350 m

15 hm + 1,2 km + 1350 m =

= 1500 m + 1200 m + 1350 m = 4050 m =

= 4050 m = 405 dam = 40,5 hm = 4,05 km

Answer 2

Răspuns:

1. 240dam=2400m

15hm=1500m

1.2km=1200m

2400m+1500m+1200m=5100m

2. 15hm=1500m

1.2km=1200m

1350m

1500m+1200m+1350m=4050m

Explicație:

1dam=10m

1hm=100m

1km=1000m
