Answer 1

Răspuns:

83 m + 176 m = 259 m

243 hm + 1 453 hm = 1.696 hm

698 dam – 509 dam = 189 dam

10 000 cm – 468 cm = 458 cm

8 x 15 cm = 120 cm

15 x 39 km = 585 km

81 mm: 9= 9 mm

56 hm : 8 = 7 hm

870 dam + 539 dam – 145 dam = 1.264 dam

6 043 mm – 1 342 mm + 27 mm = 4.728 mm

25 km x 75 +1 307 km - 493 km = 2.689 km

2 700 dm - 15 dm x 49 + 12 dm x 36 = 2.401 dm

840 cm - 72 cm : 8 - 34 x 12 cm + 56 cm : 7 = 485 cm

853 m + 81 m: 9 – 12 m: 4 x 156 = 394 m
