a)1dm = 10cm = 100mm, więc
3 dm = 30cm = 300mm
b)1m = 100cm = 1000mm, więc
8 m = 800cm = 8000mm
c)1dm = 10cm,
1cm = 10 mm, więc
500mm = 50cm = 5 dm
d)1m = 100cm,
1km = 1000m, więc
600 000cm = 6000m = 6km
zad 7
a)50m = 5000cm = 50 000mm
b)21km = 21 000m = 2 100 000cm
c)4000mm = 400cm = 4m
d)200 000cm = 2000m = 2 000 000mm
mam nadzieję, że pomogłam :)
