So, let's list the facts: 1) In a week, the eagle eats 3.85 kilograms 2) there are 7 days in a week 3) on each day, the eagle eats the same amount. This means that in order to find out how much was eaten on each day, we need to divide the whole week's food by the number of days in a week:
3.85/7= 0.55
(3.85=3.5+0.35 and 5*7=55, so (3.5+0.35)/7=0.5+0.05=0.55
