Question

Efectuează:
20 dam +5 hm=?m
7 km-4 dam=?m
36 hm + 24 hm=? km​

Answer 1

Explicație pas cu pas:

20dam + 5hm=200m + 500m =700m

7km - 4dam=7000m - 40m=6960m

36hm + 24hm= 3.6km + 2.4 km =6 km

Answer 2

Răspuns:

Explicație pas cu pas:

20 dam + 5 hm = ? m

= ( 20 × 10 ) m + ( 5 × 100 ) m =

= 200 m + 500 m =

= 700 m

_______________

7 km - 4 dam = ? m

= (7 × 1000) m - ( 4 × 10) m =

= 7000 m - 40 m =

= 6 960 m

__________________________

36 hm + 24 hm = ? km

= 60 hm =

= ( 60 : 10 ) km =

= 6 km
