Vă rog !!​

Answer 1

Parinti:300g paine

4 copii:350g×4=1400 g paine

Cate kg paine consuma parintii in 325 zile?

325 ×300=97500 g=97,5 kg paine

Cate kg paine consuma cei 4 copii in 325 zile?

325×350=113750g=113,75 kg paine

Cate kg de paine consuma toti in 325 zile?

97,5+113,75=211,25 kg

100kg grau.....130 kg paine

X kg grau.....211,25 kg paine

X=(100×211,25):130=21125:130=162,5 kg grau

Raspuns:162,5 kg grau
