A) 5388 mm 538,8 cm 5,388m 0,005388 km
B) 77452,5 mm 745,25 cm 7,4525 m 0,0074525 km
C) 75291,3 mm 7529,13 cm 75,2913 m 0,0752913 km
D) 99222 mm 922,2 cm 9,222 m 0,009222 km
E) 12 560355 mm 12 56035,5 cm 12 560,355 m 0,560355
1 km = 1000 m
1m = 10dm = 100 cm
1 dm = 10 cm
1 cm = 10 mm
B) 77452,5 mm 745,25 cm 7,4525 m 0,0074525 km
C) 75291,3 mm 7529,13 cm 75,2913 m 0,0752913 km

E) 12 560355 mm 12 56035,5 cm 12 560,355 m 0,560355
1 km = 1000 m
1m = 10dm = 100 cm
1 dm = 10 cm
1 cm = 10 mm
[tex]a) \ 5m \ 38cm \ 8mm = 5000mm + 380mm + 8mm = 5388 \ mm\\\\\\b) \ 7m \ 45 \ cm \ 25 \ mm = 7\cdot0,001km + 45\cdot0,0001km + 25\cdot0,000001km =\\\\= 0,007475 \ km[/tex]
[tex]c) \ 75m \ 29cm \ 13mm = 7500cm + 29cm + 1,3cm = 7530,3 \ cm[/tex]
[tex]d) \ 89dm \ 32cm \ 2mm =8900mm + 320mm + 2mm = 9222 \ mm[/tex]
[tex]e) \ 12560m \ 350cm \ 5mm =12,56km + 0,00035km+0,000005km = 12,560355 \ km[/tex]
Wjaśnienie:
[tex]1 \ km = 1000 \ m\\1 \ m = 10 \ dm = 100 \ cm\\1 \ cm = 10 \ mm[/tex]
