Answer 1

Plan

1)  Cate piersici a adunat Maria in cele doua cosuri ?

  45 + 32 = 77 piersici a adunat Maria

2)  Cate cutii va umple si cate piersici vor ramane in cutia care nu se completeaza?

  77 : 8 = 9 (cutii va umple )rest 5 piersici raman in cutia care nu se completeaza

Rezolvare printr-o expresie numerica in doua moduri

( 45 + 32 ) : 8 = 77 : 8 = 9 cutii ( complete cu cate 8 piersici) rest 5 piersici in cutia incompleta → primul mod

( 32: 8 ) +  ( 45 : 8 ) = 4 cutii + 5 cutii complete rest 5 piersici = 9 cutii complete ( cu cate 8 piersici ) si o cutie cu 5 piersici → al doilea mod
