In prima cutie sint 18 intregi si2\3 kg de mere,ceea ce constituie cu 3 intregi si 5\6 kg mai mult decit in cutia a doua.Cite kilograme de mere sint in cutia a treia,daca,in total,in cele trei cutii sunt 5o intregi si1\9 kg de mere?.Va rog cu schema,rezolvare .

Răspuns :

18 2/3 = (18*3+2)/3=56/3 kg in prima cutie
56/3-3 5/6 = 56/3-(3x6+5)/6=(112-23)/6=89/6 kg in cutia 2
50 1/9 =(50x9+1)/9= 451/9 kg in total
451/9 - 56/3 -89/6= (902-336-267)/18= 299/18 =16 11/18 in cutia 3
