8.a)13q=1,3t
3t-1,3t=1,7t
   b)435kg=1,35t
1,5t-1,35t=0,15t
   c)
4,5t-3t=1,5t
   d)4,4g=0,000044t
5,5t-0,000044t=5,499956
   e)280kg=2,8q
3q-2,8q=0,2q

9.compartimente=50g
   cutie=3g
   tub=1g
12 tuburi 10 compartimente
12tuburi= 12*1=>12 tuburi cantaresc 12 g
12 tuburi cu cate 10 compartimente=> 120 compartimente
120 compartimente=120*50=>120 de compartmente cantaresc 6000g
1 cutie=1*3=> 1 cutie canareste 3 g
din toate acestea=> cutia cu medicamente cantareste in total
12g+6000g+3g=6015g
