URGENT!!!!DAU CORONITAAAAAAAAAAAAAAAAAAAAA!!!!

Answer 1

300mm=30 cm
2dm=20cm
300mm+2dm=50cm

30dm=3m
42m+30dm=45m

720dam=7200m
720dam+5m=7205 m

980dm=98m
980dm-8m=90m

4×32m=128m
420dm=42m
128m-420dm= 86m

24km:3=8km
360hm=36km
8km+360hm=46km

68dm:2=34dm
570cm=57dm
34dm+57dm=91dm

72hm×6= 432hm-300m=432hm-3hm=429hm

16dm=160cm
16dm+20cm=180cm

215dm=2150cm
215dm-300cm= 1850cm

800mm:2=400mm=4dm

320dm×6= 1920dm=192m

Answer 2

300mm+2 dm=50 cm
30 cm +20 cm=50 cm

42 m+30 dm=45 m
42m+3 m=45 m

720 dam +5 m=77 m
72 m+5 m =77 m

980 dm-8 m=90 m
98 m-8 m=90 m

4×32 m - 420 dm=86 m
128 m -42 m=86 m

24 km :3+360 km=44 km
8 km +36 km=44 km

68 dm :2+570 cm=91 dm
34 dm+57 dm=91 dm

72 hm×6-300 m =429 hm
432 km -3 km =429 hm

16 dm+ 20 cm=180 cm
160 cm +20 cm =180 cm

215 dm -300 cm=185 dm
215 dm-30 dm =185 dm

800 mm:2=400 mm=4 dm

320 dm ×6=1920 dm=192 m

Sper ca te-am ajutat!
