Question

CALCULEAZA CATE KG DE NUTREȚ CONSUMA FIECARE ANIMAL ÎNTR-O ZI DACA:
6 VACI SI 2 OI CONSUMA 256 KG
9 VACI SI 5 OI CONSUMA 400 KG
METODA COMPARATIEI
( cel mai corect raspuns primeste coroana)

Answer 1

6 vaci....2 oi...256 kg/×5
9 vaci...5 oi.....400 kg/×2

30 vaci....10 oi....1280 kg
18 vaci.....10 oi....800 kg

30-18=12 vaci
1280-800=480 kg
480:12=40 kg o vaca
6×40=240kg
256-240=16 kg
16:2=8 kg o oaie
Verificam
6×40+2×8=240+16=256 prima relatie
9×40+5×8=360+40=400 a doua relatie

Answer 2

6v...2o...256 KG ( x 3 )
9v...5o...400 KG ( x 2 )

18v...6o...768 KG
18v...10o...800 KG

10 - 6 o = 4 o consuma zilnic 32 Kg ( 800 - 768 )
32 : 4 = 8 kg consuma zilnic o oaie

256 - 16 = 240 kg consuma zilnic 6 vaci .
240 : 6 = 40 kg o vaca zilnic
