284кг=284000гр

284000:5=56800 (гр) съели в первый день

1) 284*15=56,8 кг - съели в первый день

2) 284-(56,8+98,4)=284-155,2=128,8 кг - осталось

Ответ: осталось 128 кг 800 г.

Можно все перевести в граммы - 1кг=1000г, 284 кг=284000г, 98 кг 400г=98400г

1) 284000*15=56800 г - в первый день

2) 284000-(56800+98400)=128800 г=128 кг 800г
