Question

va rog sa ma ajutati=3​

Answer 1

Răspuns:

760 mm

400 dm

500 dam

2300 dm

2 m

Explicație pas cu pas:

a. 19 cm x 4 = 76 cm

76 cm = 76 x 10 mm = 760 mm

b. 280 m : 7 = 40 m

40 m = 40 x 10 dm = 400 dm

c. 2 km + 30 hm = 2 km + (30 : 10 km) = 2 km + 3 km = 5 km

5 km = 5 x 100 dam = 500 dam

d. 30 dam - 70 m = 30 dam - (70 : 10 dam) = 30 dam - 7 dam = 23 dam

23 dam = 23 x 100 dm = 2300 dm

e. 10 dm x 2 = 20 dm

20 dm = 20 : 10 m = 2 m

Sa speram ca nu am gresit! :>
