Explicație pas cu pas:
3 m + 2000 mm = 3000 mm + 2000 mm = 5000 mm
5000 m + 7 km = 5 km + 7 km = 12 km
980 hm + 78000 m = 98 km + 78 km = 176 km
8 m - 2450 mm = 800 cm - 245 cm = 555 cm
8 m - 155 cm = 800 cm - 155 cm = 645 cm
900 cm - 370 mm = 9000 mm - 370 mm = 8630 mm
8 x 35 hm = 280 hm = 28 km
900 mm : 5 = 180 mm = 18 cm
Răspuns:
3m+2000mm= 3000mm+2000mm= 5000mm
5000m+7km= 5km+7k=12km
980hm+78.000m=98km+78km= 176km
8m-2450mm=80cm-245cm= -165cm
500cm-2m=500cm-200cm=300cm
8m-155cm=800cm-155cm=645cm
900cm-370mm=9000mm-370mm=8630mm
8×35hm=280hm=28km
900mm÷5=180mm=18cm
Iar la prima : 7m+400cm=7m+4m=11m
