Answer: 15.4 kilograms of food.
Step-by-step explanation:
Since there are 1000 grams in a kilogram, we can just divide the gram content of each box by 1000. In the first box, there are twenty bags of 450-gram bags of pasta. We can multiply 450*20, since there are twenty bags of pasta in total, and we would get 9000, or 9000 grams of pasta in the first box. If you divide that by 1000, you will get 9. There are 9 kilograms of food in the first box.
As for the second box, there are sixteen 400-gram cans of beans. 16*400 is 6400, which is the total amount of grams in the second box. Divide that by 1000, and we get 6.4. There are 6.4 kilograms of food in the second box.
If you add the total kilograms of each box together, you will get 15.4 kilograms of food in total.
