Final answer:
To find out how many kilograms of apples are needed for three apple pies, we multiply the amount of sliced apple required for one pie (750 g) by the number of pies (3) and convert the result to kilograms. The answer is 2.25 kg of apples.
Step-by-step explanation:
To find out how many kilograms of apples are needed for three apple pies, we need to multiply the amount of sliced apple required for one pie (750 g) by the number of pies (3) and then convert the result to kilograms.
First, multiply 750 g by 3: 750 g x 3 = 2250 g.
Next, convert 2250 g to kilograms by dividing by 1000: 2250 g ÷ 1000 = 2.25 kg.
Therefore, 2.25 kilograms of apples are needed for three apple pies.
