Question

va rog ex 10 dau coroana​

Answer 1

a) 1,2 cm = 12 mm

0,1 dm = 10 mm

P = 12 mm + 10 mm + 20 mm = 42 mm

b) 1300 cm = 13 m

0,1 hm = 10 m

P = 13 m + 10 m + 21 m = 44 m

c) 0,25 hm = 25 m

3,1 dam = 31 m

P = 25 m + 31 m + 12 m = 68 m

d) 2,8 dam = 280 dm

11,5 m = 115 dm

1550 cm = 155 dm

P = 280 dm + 115 dm + 155 dm = 550 dm
