1 centimeter (cm) = 10 milimeters (mm)

1 decimeter (dm) = 10 cm

1 meter (m) = 10 dm

1 m = 100 cm = 1000 mm.

1 kilometer (km) = 1000 m

1 cm = 1/100 m

1 mm = 1/10 cm

1 m = 1/1000 km

 

  Complete the following:
Solutions
1) 1 m 2 dm = __120__ cm; 1 m = 100 cm; 2 dm = 2 x 10 cm = 20 cm ; 100 cm + 20 cm = 120 cm.
2) 2 m = 20 dm 2 m = 2 x 10 dm = 20 dm
3) 2 cm= 20 mm 2 cm = 2 x 10 mm = 20 mm
4) 3 m = 300 cm 3 m = 3 x 100 cm = 300 cm
5) 4 m = 4000 mm  4 m = 4 x 1000 mm = 4000 mm
6) 3 m 2 dm = 320 cm

3 m =3 x 100 cm = 300 cm; 2 dm = 2 x 10 cm = 20 cm ;
300 cm + 20 cm = 320 cm

7) 2 m 30 cm = 2300 mm 2 m = 2 x 1000 mm = 2000 mm; 30 cm = 30 x 10 mm = 300 mm; 2000 mm + 300 mm = 2300 mm
8) 1 m 2 mm = 1002mm 1 m = 1000 mm; 1000 mm + 2 mm = 1002 mm
9) 3 km = 3000 m 3 km = 3 x 1000 m = 3000 m
10) 2 km = 200,000 cm 2 km = 2 x 1000 m = 2000 m; 1 m = 100 cm; 2 km = 2 x 1000 x 100 cm = 200,000 cm
11) 1 km 2 m = 1002 m 1 km = 1000 m; 1000 m + 2 m = 1002 m
