Toate exercițiile incercuiteeee. DAU COROANA!!!

Answer 1

7)57x10=570
390:10=39
107x10=1070

7900:100=79
330x100=3300
800x100=80000

25x1000=25000
890x1000=890000
6000:1000=6

230:10=23
450x10=4500
907x10=9070

8)560hm=560x10=5600 dam
350dam=350:10=35 hm
1200dam=1200:100=12 km
45km=45x100=45dam
600dam=600:100=6km
1200dam=1200:10=120hm


10)a)
12hm-3200cm+730dam=12x100-3200:100+730x10=1200-32+7300=8532m

B)130hm+12000m-800dam=130:10+12000:1000-800:100=13+12-8=17km

C)13000mm+79hm-480dm=13000:1000+79x100-480:10=13+790-48=755m

D)31km+45hm-700m=31x100+45x10-700:10=3100+450-70=3480dam

12)L=7m
25cm=0,25m
7m.......x bucati
0,25m....1 bucata

0,25x=7x1
X=7:0,25
X=28 de bucati se obțin

7:25/100=7x100/25=700/25=28
700:25=28
