Answer 1

\(135m=1350dm\)

\(342dm=3420cm\)

\(4km37m=4037m\)

\(8m12cm=812cm\)

\(8300m=830dam\)

\(4000m=40hm\)

\(25000m=25km\)

\(354dm=35m4dm\)

\(3040m=3km40m\)

\(1mm=0,1cm\)

\(1cm=0,01m\)

\(1m=0,001km\)

Answer 2

\(1\)

a

135 m = 1350 dm

342 dm = 3420 cm

15 cm=150 mm

b

8300 m = 830 dam

4000 m = 40 hm

25000 m = 25 km

c

1mm = 0,1 cm

1 cm = 0,01 m

1 m = 0,001 km

\(2\)

a

4 km 37 m = 4037 m

8 m 12 cm = 812 cm

354 dm = 35 m 4 dm

3040 m = 3 km 40 m
