Explicație pas cu pas:
1m = 10 dm = 100 cm = 1000 mm
Prima coloană:
1/2 m = 1/2 × 10 dm = 5 dm
1/2 m = 1/2 × 100 cm = 50 cm
1/2 m = 1/2 × 1000 mm = 500 mm
A treia coloană:
2/5 m = 2/5 × 10 dm = 4 dm
2/5 m = 2/5 × 100 cm = 40 cm
2/5 m = 2/5 × 1000 mm = 400 mm
A patra coloană:
3/5 m = 3/5 × 10 dm = 6 dm
3/5 m = 3/5 × 100 cm = 60 cm
3/5 m = 3/5 × 1000 mm = 600 mm
