a) 135m=1350dm b) 8300m=830dam c) 1mm=0.1cm
342dm=3420cm 4000m=40hm 1m=100cm
15cm=150mm 2500m=25km 1m=0.001km
a)
135 m = 1350 dm
342 dm = 3420 cm
15 cm = 150 mm
b)
8300 m = 830 dm
4000 m = 40 hm
25000 m = 25 km
c)
1 mm = 0,1 cm
1 cm = 0,01 m
1 m = 0 , 001 km
( bằng cách tk và kb nhé! thanks)
135 m = 1350dm 8300m=830dam 1mm=1/10cm=0,1cm
342dm=3420cm 4000m=40hm 1cm=1/10 dm =0,1 dm [nếu bạn viết nhầm]
15cm=150mm 25000=25km 1m=1/1000km=0,001km
135m=1350dm 8300m=83dam 1mm=0,001cm
342dm=3420cm 4000m=40hm 1cm=1cm
15cm=150mm 25000m=25km 1m=0,001km
k mình nha
a) 135m = 1350dm
342dm = 3420cm
12cm = 150mm
b) 8300m = 830dam
4000m = 40hm
25000m = 25km
c) 1mm = \(\frac{1}{10}\)cm = 0.1cm
1cm = 1cm
1m = \(\frac{1}{1000}\)km = 0.001km
a) 135m = 1350dm b)8300m = 830dam c)1mm = 0,1cm
342dm = 3420cm 4000m = 40hm 1cm= 1,0 cm
15cm = 150mm 25000m = 25km 1m = 0,001km
