Answer 1

Explicație pas cu pas:

a) 13 dam + 170 dm = 1300dm+ 170dm = 147 dm

9 km + 15 m = 9000 m + 15 m = 9015 m

63 hm - 1 300 cm = 630000 cm - 1300 cm = 628700 cm

18 dm-5 cm = 180 cm - 5 cm = 175 cm

b) 13 km + 400 dm = 130000 dm + 400 dm = 130400 dm

23 hm - 4 000 dm= 23000 dm - 4000 dm = 19000 dm

63 hm - 1 300 cm = 63 0000 cm - 1300 cm = 628700 cm

18 dm - 50 cm = 180 cm - 50 cm = 130 cm

c) 570 hm : 3 = 190 hm

64 000 m: 4 = 16 000 m

16 km x 3 = 48 km

7 cm x 21 = 147 cm

d) 16 x 15 dam = 240 dam

70 dm : 2 = 35 dm

165 000 cm : 3 = 55 000 cm

20 000 m: 5 = 4000 m
