[tex]1.lingurita=100g=\ \textgreater \ 5lingurite-\ \textgreater \ 100*5=500g \\ \\ 2linguri-\ \textgreater \ 500g=5lingurite-\ \textgreater \ 500g \\ \\ 4linguri+4lingurite=?g=\ \textgreater \ 4linguri=500*2-\ \textgreater \ 4linguri=1000g \\ 1000g+4lingurite(4*100=400g)=1.400g \\ \\ Raspuns:4linguri+4lingurite=1000+400 \\ =1.400g(1kg,400g)[/tex]

Answer 2

100x5=500(g cantaresc 5 lingurite)
500:2=250(g cantareste o lingura)
(100x4)+(250x4)=400+1.000=1.400(g cantaresc 4 lingurite si 4 linguri)
