Question

Calculează , după model.
a. 8km+15dam=
b. 250dm+4dam=
c. 19hm+2 500dm=

Answer 1

a. 8 km + 15 dam = ? m

8 km = 8000 m

15 dam = 150 m

8000 m + 150 m = 8150 m

-------------------------------------------------

b. 250 dm + 4 dam = ? m

250 dm = 25 m

4 dam = 40 m

25 m + 40 m = 65 m

----------------------------------------------

c. 19 hm + 2500 dm = ? dam

19 hm = 190 dam

2500 dm = 25 dam

190 dam + 25 dam = 215 dam
