A cookie recipe requires a total of 0.8 kg of flour. Flour is only sold in small bags that contain 150 g each. How many small bags of flour are needed to make the recipe?
Step 1: Convert the total required mass to the same unit as the bags (grams). 0.8 kg = 800 g
Step 2: Determine the final number of bags. Since you cannot buy a fraction of a bag, you must round up to the nearest whole number to ensure you have enough flour. 5 bags will give you 5 x 150 g = 750 g → not enough 6 bags will give you 6 x 150 g = 900 g → enough
Answer: 6 small bags of flour are needed.
