Answer 1

10.
a) 12 hm - 3 200 cm + 730 dam = 1 200 m - 32 m + 7 300 m = 8 468 m
b) 130 hm + 12 000 m - 800 dam = 13 km + 12 km - 8 km = 17 km
c) 13 000 mm + 79 hm - 480 dm = 13 m + 7 900 m - 48 m = 7 865 m
d) 31 km + 45 hm - 700 m = 3 100 dam + 450 dam - 70 dam = 3 480 dam

Answer 2

10)

a) 12 hm - 3 200 cm + 730 dam = 8 468 m

= 1 200 m - 32 m + 7 300 m =

= 1 168 m + 7 300 m =

= 8 468 m

b) 130 hm + 12 000 m - 800 dam = 17 km

= 13 km + 12 km - 8 km =

= 25 km - 8 km =

= 17 km

c) 13 000 mm + 79 hm - 480 dm = 7 865 m

= 13 m + 7 900 m - 48 m =

= 7 913 m - 48 m =

= 7 865 m

d) 31 km + 45 hm - 700 m = 3 480 dam

= 3 100 dam + 450 dam - 70 dam =

= 3 550 dam - 70 dam =

= 3 480 dam
