704 mm = 0,704 m

1534 mm = 1,534 m

900 m = 0,9 km

thanks

cho mik hỏi cái đềbài :

mik ko hiểu lắm

0,5 dm = 0,05 m = 500 mm

2,1 cm = 0,021 m = 0,21 dm

0,05 m = 50 mm = 5 cm

4,52 mm = 0,0452 dm = 0,452 cm

Học vui nha !
^^

0,5 dm = 0,05 m = 50 mm

2,1 cm = 0,021 m = 0,21 dm

0,05 m = 50 mm = 5 cm

4,52 mm = 0,0452 dm = 0,452 cm

giúp mình bạn nhé\n\n75km 234m =……..km\n9dm 8cm 6mm=……dm\n3m 6dm 4cm=……..m\n6dm 6mm=……..dm\n2,538m=…….m…..dm……cm………mm\n2,538m=…….m……cm…….mm\n2,538m=…….m…..mm\n7,306m=……m…….dm…..mm\n7,306m=……m…….cm……mm\n7,306m=……m…….mm\n7,306m=……mm\n2,586km=…….km……m\n2,586km=…….m\n8,2km=…….km……..m\n8,2km=…….m\n4m 25cm=……m\n9dm 8cm 5mm=…………dm\n2m 6dm 3cm=………m\n4dm 4mm=………..dm\n1,105kg=………g\n5,6kg……….g\n9,05kg=………g\n0,01kg=……g\n0,003kg=…….g\n0,078kg=………g\n\n\

toán 5

1) 20km = 20000000mm

60cm = 600mm

8000m=8km

6000 mm =6m

2) 82mm = 52m + 50m-20m

75cm = 65cm-15cm+25cm

1. 20km = 20000000mm

60cm = 600mm

8000m=8km

6000 mm =6m

2. 82mm = 52m + 50m-20m

75cm = 65cm-15cm+25cm

0,309

0,309m
