Answer 1

Răspuns:

Explicație pas cu pas:

26 m + 320 dm - 800 cm = ? m

= 26 m + 32 m - 8 m =

= 58 m - 8 m =

= 50 m

____________________________

320 dm = (320:10) m = 32 m  ( dm < m de 10 ori )

800 cm = (800:100)m = 8 m    ( cm < m de 100 de ori )

___________________________________________

4 000 ml + 2 l - 30 dl = ? l ( litri )

= 4 l + 2 l - 3 l =

= 6 l - 3 l =

= 3 l

4000 ml = (4000 : 1000 ) l = 4 l ( ml < litru de 1 000 de ori )

30 dl = (30:10)l = 3 litri ( dl < l de 10 ori )

_______________________________________________

800 hg × 5 + 20 kg = ? kg

= 4 000 hg + 20 kg =

= 400 kg + 20 kg =

= 420 kg

4000 hg = ( 4000:10)kg = 400 kg   ( hg < kg de 10 ori )
