3m+20cm=?cm
3 m =300 cm
300 cm+20 cm=320 cm
7m+400cm=?m
400 cm=4 m
7 m+ 4 m =11 m
3m+2000mm=?mm
3 m=3 000 mm
3 000 mm + 2 000 mm= 5 000 mm
5000m+7km=?km
5 000 m=5 km
5 km + 7 km = 12 km
980hm+78000m=? km
980 hm = 98 km
78 000 m = 7i km
98 km + 78 km= 176 km
8m-2450mm=?cm
8 m = 800 cm
2 450 mm = 245 cm
800 cm - 245 cm=555 cm
70km-45000m=?m
70 km = 70 000 m
70 000 m - 45 000 m = 25 000 m
500cm-2m=?cm
2 m = 200 cm
500 cm - 200 cm = 300 cm
8m-115cm=?cm
8 m = 800 cm
800 cm - 115 cm = 685 cm
900cm-370mm=?mm
900 cm = 9 000 mm
9 000 mm - 370 mm =8 630 mm
8x35hm=?km
35 hm = 3,5 km
8×3,5 km=28 km
900mm:5=?cm
900 mm = 90 cm
90 cm :5=18 cm

I + II + III = 720 km
I + II = 463 km
inlocuim.....
463 km + III = 720 km
III = 720 km - 463 km
III = 257 km (a parcurs a treia zi)
I + II + III = 720 km
II + III = 545 km
inlocuim.....
I + 545 km = 720 km
I = 720 km - 545 km
I = 175 km (a parcurs prima zi)
I + II + III = 720 km
I = 175 km (a parcurs prima zi)
III = 257 km (a parcurs a treia zi)
inlocuim.....
175 km + II + 257 km = 720 km
175 km + II = 720 km - 257 km
175 km + II = 463 km
II = 463 km - 175 km
II = 288 km (a parcurs a doua zi)
