La un oficiu postal s-au adus 18 colete de cite 5 kg fiecare si 17 colete de cîte 8 kg fiecare.Cit cintaresc coletele in total?


Răspuns :

18 colete --- 5 kg
16 colete --- 8 kg
..............................
18×5= 90 kg
17×8= 136 kg
 90 kg + 136 kg = 226 kg
................................................
Coletele cantaresc 226 kg in total.

(18x5)+(17x8)=90+136=226
R: in total coletele cantaresc 226 kg.
