1 tona = 1000 kg = 1000 *1000 = 1 000 000 gram
3 t 20 g = 3 000 020 g = 3,000002t
1 km = 1000 m = 1000 *100 = 100 000 cm
2 km 50 cm = 200 050 cm = 2,00005 km
1 tona = 1000 kg
10t i 10 kg = 10 010 kg = 10,0001 t
a) 1t=1000kg*1000=1000000g
1kg=1000g
czyli:
3t=3000000g +20g= 3000020g
3,00002t
b)
1km = 1000m
1m = 100cm
czyli:
2km = 2000m*100= 200000cm
200000cm+50cm= 200050cm
2,0005km
c)
1t=1000kg
10*1000kg= 10000kg
10000kg+10kg= 10010kg
10010kg=10,1t
mam nadzieje ze pomogłam i jest dobrze :)
