Answer 1

Răspuns:

a) 5 l + 8 dl = ? dl

5 l = 50 dl

50 dl + 8 dl = 58 dl

23 dam + 450 dm = ? m

23 dam = 230 m

450 dm = 4500 m

230 m + 4500 m = 4730 m

35 kg - 230 g = ? g

35 kg = 35000000 g

35000000 g - 230 g = 34999770 g

b) 600 mm - 40 cm = ? dm

600 mm = 6 dm

40 cm = 4 dm

6 dm - 4 dm = 2 dm

90000 l - 40 kl = ? hl

90000 l = 900 hl

40 kl = 400 hl

90000 l = 900 hl

900 hl - 400 hl = 500 hl

2900 dag + 7 q = ? kg

2900 dag = 290 kg

7 q = 700 kg

290 kg + 700 kg = 990

c) 45 kg × 6 = ? g

45 kg = 45000 g

4500 g × 6 = 27000 g

360 t ÷ 9 = ? kg

360 t = 3600 kg

3600 kg ÷ 9 = 400 kg

45 m × 15 = ? dm

45 m = 450 dm

450 dm × 15 =6750 dm

Sper ca este bine! Baftă!
