Give the step-by-step reasoning process and then the final answer. A store sells 20 packets of 100 grams of sugar every week. How many kilograms of sugar does it sell every week?
A total of 20 x 100 = 2000 grams are sold every week. Since 1 kilogram is equal to 1000 grams, then 2000 / 1000 = 2 kilograms of sugar are sold every week.
The final answer: 2.
