Final answer:
By converting 2.4 kg to grams and dividing by the weight of one cup of flour (120 grams), one can obtain 20 cups of flour from a 2.4 kg bag.
Step-by-step explanation:
To determine the number of cups of flour you can get from a 2.4 kg bag, knowing that one cup of flour weighs approximately 120 grams, you first need to convert the weight of the bag from kilograms to grams. Since there are 1000 grams in one kilogram, a bag of flour weighing 2.4 kg is equal to 2400 grams (2.4 kg × 1000 g/kg).
Now, you divide the total weight of the bag in grams by the weight of one cup of flour:
2400 g ÷ 120 g/cup = 20 cups
This means you can get 20 cups of flour from a 2.4 kg bag.
