a) 20 m+2 dam+31 dm=20 dm+200 dm+31 dm=251 dm

b) 36 cm+120 mm-2 dm =36 cm+12 cm-20 cm=28 cm

c) 148 hm -1 km+240 dam+50 m=

1480 dam-100 dam+240dam+5dam=1625 dam

d) 76 dam - 25 m + 1800 dm=760 m-25 m+180 m=915 m

e) 2600 cm + 17000 mm-15 m=260 dm+170 dm -150 dm=280 dm

f) 640 hm + 24 dam - 150 m=6400 dam+24 dam-15 dam=6409 dam
