Bagai mana caranya: 8 hm - 200 m = m 800 m - 2 hm = m 300 m + 5 dam = m

1. 8hm - 200 m = ... m
1 hm = 100 m
Maka 8 hm = 8 x 100 = 800 m
800m - 200m = 600m

2. 800 m - 2 hm = ... m
800 m - 2 x 100m = 800m - 200m
= 600 m

3. 300 m + 5 dam = ... m
1 dam = 10 m
5 dam = 5 x 10m = 50 m
300m + 50m = 350 m
