Question

intr_o punga sunt 3 1/2kg mere,iar in alta cu 5 3/4 kg mai mult.Cate kg de mere sunt in cele doua pungi?

Answer 1

[3·2+1]/2=[6+1]/2=7/2=3,5[kg-prima punga];
⇒a=3,5kg[mere];
3,5+[5·4+3]/4=3,5+23/4=3,5+5,75=9,25[kg-a doua punga];
⇒b=9,25kg[mere];
⇒a+b=3,5kg+9,25kg=12,75[kg-mere sunt in cele doua pungi in total];
