Answer 1

Răspuns:

Explicație pas cu pas:

7 m + 400 cm = 7 m + 4 m = 11 m

3 m + 2000 mm = 3 m + 2 m = 5 m

5000 m + 7 km = 5 km + 7 km = 12 km

980 hm + 78000 m = 980 hm + 780 hm = 1760 hm

8 m - 2450 mm = 8000 mm - 2450 mm = 5550 mm

70 km - 45000 m = 70 km - 45 km = 25 km

500 cm + 2 m = 5 m + 2 m = 7 m

8 m - 155 cm = 800 cm - 155 cm = 645 cm

900 cm - 370 mm = 900 cm - 37 cm = 863 cm

8 x 35 hm = 280 hm

900 mm : 5 = 180 mm
