Answer:
10.54 kg
Explanation:
As the statement indicates that at breakfast they served half of the blueberries and at dinner they put the remaining 5,270 g, you have to multiply that amount for two to find the amount of blueberries they had at the beginning:
5,270 g *2= 10,540 g
Considering that the question is asking for the amount of kg of blueberries, we have to convert from g to kg:
1 kg → 1,000 g
x ← 10,540 g
x= (10,540 * 1)/1,000= 10.54 kg
