At science camp the kitchen served half of their blueberries with breakfast. after dinner they put the remaining 5,270g of berries on top of their ice cream dessert. how many kg of blueberries did the science camp start with?

10.54 kg

Step-by-step 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
