Question

cum se rezolva exercitiile? : 9600cm - ?mm =80m,34 hm - ?cm = 337dam,88dm - ?dm = 5300 mm si 124 km + ? hm = 1298 hm...va rog sa imi raspundeti!multumesc

Answer 1

 a)9600cm -X mm =80m
transformi cm si m in mm   9600 cm=96000mm iar 80m=80000mm

96000mm-Xmm=80000mm
X=96000mm-80000mm
X=16000mm
b)34hm-Xcm=337dam 
transformi hm si dam in cm  34hm=340000cm  337dam=3370cm
340000cm-Xcm=3370cm
X=340000cm-3370cm
X=336630cm
c)88dm-Xdm=5300mm
transformam mm in dm   5300mm=53dm
88dm-Xdm=53dm
X=88dm-53dm
X=35dm
d)124km=Xhm=1298hm
transformam km in hm 124km=1240hm
1240hm-Xhm=1298hm
X=1240hm-1298hm
X=-54
