Question

Scrie, pe spatiile punctate, numerele care fac egalităţile adevărate.
7 dm + 50 cm + ... mm = 14 dm
...q+15 t +6800 kg = 281 q
1 m -... cm + 280 mm = 580 mm
10t - 10 q- ... kg = 8t
1 dl + 80 c - ... ml = 111 ml
...t-29 - 4500 kg = 14 300 kg
... ml + 68 cl - 6 dl = 10 cl
228 q + 27 kg - ... t= 2827 kg​

Answer 1

7 dm + 50 cm + ... mm = 14 dm transformam tot in mm

700mm+500mm+.....mm=1400mm

deci lipseste 200 mm

...q+15 t +6800 kg = 281 q transformam tot in q

....q+150q+68q=281q

deci lipseste 281-218=63q

1 m -... cm + 280 mm = 580 mm transformam tot in cm

100cm-....cm+28cm=58cm

deci lipseste 70 cm

10t - 10 q- ... kg = 8t transformam tot in kg

10000kg-1000kg-....kg=8000kg

deci lipseste 1000 kg

1 dl + 80 cl - ... ml = 111 ml transformam tot in ml

100ml+800ml-...ml=111ml

deci lipseste 789ml

...t-29 - 4500 kg = 14 300 kgtransformi tot in t

ai uitat o unitate de masura

... ml + 68 cl - 6 dl = 10 cl transformi tot in ml

...ml+680ml-600dl=100ml

deci lipseste 20 ml

228 q + 27 kg - ... t= 2827 kg transformi tot in t

22,8 t + 0,027t -... t=2,827 t

deci lipseste 20 t
