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!
