Question

750dam-2hm=.......km
475hm-1,5km=......dam
1,25hm-20dam=.....m

Answer 1

750 dam = 0,75 km
2 hm = 0,2 km
0,75 km - 0,2 km = 0,55 km

475 hm = 4750 dam
1,5 km = 150 dam
4750 dam - 150 dam = 4600 dam

1,25 hm = 125 m
20 dam = 200 m
125 m - 200 m = -75 m

Answer 2

750dam - 2hm=7.5km - 0.2km= 7.7km
475hm - 1.5km= 4750dam - 150dam = 4600dam
1.25hm - 20dam= 125m - 2m = 123m
