Final answer:
To convert the mass of Lorena's backpack from grams to kilograms, divide 22,000 grams by 1,000, resulting in a mass of 22 kilograms for the backpack.
Step-by-step explanation:
Lorena's backpack has a mass of 22,000 grams. To convert grams into kilograms, we need to divide the mass in grams by 1,000, since 1 kilogram is equivalent to 1,000 grams. So, we perform the following calculation:
Mass in kilograms = Mass in grams ÷ 1,000
Mass in kilograms = 22,000 g ÷ 1,000
Mass in kilograms = 22 kg
Therefore, the mass of Lorena’s backpack in kilograms is 22 kg.
