Question

38 dam=.... m= .....hm
2.500m= ....cm=....dam
7 km=....hm = ..... dm
1.13 dm = mm=m
0,5 km'3 = dam'3
VĂ ROGGGGGGGGG ​

Answer 1

Răspuns:

Explicație pas cu pas:

38 dam=38×10 m=380m

38dam=38:10 hm= 3,8hm

2.500m= 2500×100cm=250000cm

2500m=2500:10dam =250dam

7 km=7×10hm=70hm

7km= 7×1000m=7000m=7000×10=70000dm

1.13 dm = 1,13×100mm=113mm

1,13dm=1,13:10m=0,113m

0,5 km'3 = 0,5 × 1000 hm'3 =

=500 hm'3=500 ×1000dam'3=500000dam'3

Presupun ca '3 inseamna la a treia

_______________

Atunci cand "mergi in sus" (catre multiplii) imparti cu 10 daca e vorba de metri, cu 100 daca sunt metrii patrati si cu 1000 daca sunt metrii cubi.

Atunci cand mergi in jos, catre submultiplii inmultesti

Answer 2

Răspuns:

38 dam =380m=3,8hm

2500m=250000cm=250dam

7km=70hm=70000dm

113 dm =11300mm=11,3m

0,5km'3=500000km'3
