Answer 1

Răspuns:

Explicație pas cu pas:

32hg-100dg=320 dag - 1 dag = 319 dag,

5m+20dm-685cm= 500 cm + 200 cm - 685 cm = 15 cm,

90l-(4600cl:2+38 000ml)= 90l - (23l + 38l) = 90l - 61l = 29l,

13dm+2cm= 130 cm + 2 cm = 132 cm,

1h-8min= 3600 s - 480 s = 3120 s,

4km+3dam+2hm= 4000 m + 30m + 200 m = 4230 m,

9000ml-30dl= 900 cl - 300 cl = 600 cl,

5h 15min-3h 40 min= 4h 75min - 3h 40 min = 1h 35 min,

4t-150kg=4000 kg - 150 kg = 3850 kg,

2dag+700dg= 20 g + 70 g = 90 g,

3secole-125ani=300 ani - 125 ani = 175 ani.
